Question 1
ప్రశ్న 1
Under IRC:67-2022, which combination correctly identifies the usual shapes of mandatory or regulatory, cautionary or warning, and informatory or guide signs, while recognising the right-of-way exceptions?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The road-sign system uses readily recognisable shapes to communicate different functions. Regulatory signs are generally circular and convey requirements, restrictions or prohibitions. Warning signs are generally upright triangular and alert users to a hazard ahead. Guide and informatory signs generally use rectangular formats. STOP is octagonal and GIVE WAY is an inverted triangle, making them exceptions to the usual regulatory shape.

Question 2
ప్రశ్న 2
An engineer must specify the two special regulatory right-of-way signs at priority-controlled junctions. Which shape and principal colour combination is correct under IRC:67-2022?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
STOP and GIVE WAY both regulate priority at intersections. The STOP sign uses a distinctive octagonal shape with a red background and white lettering and border. The GIVE WAY sign uses an equilateral triangle pointing downwards with a red border and white background. Their shapes help users recognise the instructions promptly. They should not be replaced by the ordinary circular regulatory format.

Question 3
ప్రశ్న 3
At a minor-road approach to a high-speed major road, restricted sight visibility and adverse crash experience make compulsory stopping necessary before entry. Which signing treatment is most appropriate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The site assessment states that a full stop is necessary before vehicles enter the major road. A STOP sign therefore conveys the required control more directly than a conditional yield instruction. IRC signing practice associates it with appropriate stop-line and pavement markings. The sign should be placed where approaching drivers can see it without blocking their view of major-road traffic. Further advance warning may be warranted if the STOP sign itself cannot be seen adequately.

Question 4
ప్రశ్న 4
A dual-carriageway exit ramp joins a one-way road, and field reports show drivers mistakenly entering the ramp against the permitted direction. Which sign should face drivers at the prohibited entry point?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The immediate problem is an attempted entry where vehicle movement is prohibited. A NO ENTRY regulatory sign is intended to face road users who might enter the road or ramp in the wrong direction. The sign must be oriented so that it does not confuse traffic to which it does not apply. ONE WAY information can complement the signing arrangement but does not replace the prohibition at the wrong entry. Site geometry and visibility should also be reviewed to reduce the opportunity for an erroneous movement.

Question 5
ప్రశ్న 5
A road agency wants to prohibit right turns at a junction but also to warn drivers about a sharp right-hand horizontal curve on a different approach. Which interpretation correctly separates the two sign functions?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A turn prohibition prescribes a movement that road users must not make. It is consequently a regulatory function. A sharp horizontal curve is a geometric condition that may require drivers to reduce speed and exercise caution. Such a condition is addressed by an appropriate warning sign and any justified supplemental delineation. Confusing these functions can cause drivers to misunderstand whether an action is forbidden or whether a hazard lies ahead.

Question 6
ప్రశ్న 6
At a channelized traffic island, drivers are required to pass to the left of the obstruction. Which sign family and visual treatment is appropriate for this positive mandatory movement instruction?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A required direction of travel is a positive mandatory instruction. IRC:67-2022 distinguishes compulsory-direction signs from red-bordered prohibitory signs. Such compulsory signs have a circular format and use white symbols on blue. They guide vehicles along the designated side of a traffic island or similar obstruction. The sign position must still provide adequate recognition and clearance for approaching vehicles.

Question 7
ప్రశ్న 7
An engineer specifies a statutory maximum-speed indication for entry into a road section. Which sign type best conveys the maximum permitted speed, rather than merely advising about a hazard?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A maximum permitted speed is a regulatory restriction, not merely a description of road geometry. IRC:67-2022 provides speed-limit signs with circular shapes, red borders and black numerals on white. The restriction must be signed at an appropriate location where it begins and repeated when required. A warning sign for a nearby curve serves a different function from the maximum-speed restriction. The adopted limit must be supported by appropriate traffic-engineering assessment and applicable authority.

Question 8
ప్రశ్న 8
A road passes a school where crossing activity makes approaching traffic a hazard to children. Which statement captures a specific colour provision of IRC:67-2022 for the School Ahead warning sign?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
School Ahead is a cautionary sign used where school-related conditions create a hazard for children. The 2022 road-sign code specifically calls for a fluorescent yellow-green background for this sign. This special provision improves conspicuity and is important when interpreting the general warning-sign colour convention. The sign itself does not impose a universal stop requirement on every passing vehicle. Suitable crossing facilities, operating speeds and any supplementary school-time information still require site-specific assessment.

Question 9
ప్రశ్న 9
An engineer designs temporary destination and diversion information signs for a major highway work zone. Under the colour-pattern schedule for direction information in IRC:67-2022, which pairing is appropriate for temporary or work-zone information signs?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The road-sign code uses different colour patterns for different direction-information contexts. Temporary or work-zone direction information is assigned a yellow background with black content. This helps distinguish temporary guidance from standard permanent route signing. It should not be confused with the separate design rules for regulatory signs or hazard-warning signs. Consistent placement and removal of obsolete temporary signs are important for safe navigation through the work zone.

Question 10
ప్రశ్న 10
On an otherwise normal-width two-lane road, an approaching bridge has a clear carriageway width smaller than that of the road. No height or axle-load restriction has been identified. Which warning is most directly appropriate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The identified hazard is the reduction in available roadway width at the bridge. A Narrow Bridge Ahead warning sign alerts approaching drivers to this physical constraint. The sign should be positioned far enough in advance for recognition and an appropriate response. A height-limit sign would address a different restriction and should not be invented without a verified clearance limitation. Additional markings and delineation may be necessary depending on bridge geometry and traffic conditions.

Question 11
ప్రశ్న 11
A proposed underpass has a verified overhead clearance restriction for certain tall vehicles. Which sign addresses the enforceable vehicle-dimension restriction most directly?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A known overhead clearance constraint must be communicated before an overheight vehicle enters the restricted section. A height-limit sign is a regulatory vehicle-control sign. The displayed restriction must reflect the authorised safe clearance for the facility. It is different from a warning about a reduced carriageway width. Where alternate routes are available, advance guidance may also be needed so affected vehicles can divert safely.

Question 12
ప్రశ్న 12
According to the road-type direction-sign colour scheme in IRC:67-2022, which pair is correct for ordinary route-direction signs on a National Highway and on an Expressway, respectively?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
IRC:67-2022 prescribes a road-type-based colour scheme for direction information. The normal National Highway direction sign uses green with white lettering and arrows. Expressway direction information uses blue with white content. The convention helps drivers interpret signs consistently within a road network. Different colours can apply to tourism, temporary traffic management and other special guidance contexts.

Question 13
ప్రశ్న 13
A highway tourism plan requires advance direction information for a designated heritage destination, while also guiding vehicles to a nearby fuel station. Which distinction is correct under IRC:67-2022?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Tourism-related direction information has a distinct brown-and-white colour scheme. Facility information is separately designed to identify services such as fuel and food. Standard facility boards are rectangular with a blue field and a symbol presented in a white area. Their role is guidance rather than imposing a traffic prohibition. Combining signs must still preserve clear priorities, reading time and correct destination information.

Question 14
ప్రశ్న 14
An agency is preparing permanent direction signs for an urban city road and a village road. Which background-and-lettering combinations follow IRC:67-2022?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The sign code varies direction-information colours with the category of road. Urban and city-road direction boards normally use a blue background with white content. Direction information on other district and village roads uses white with black. These are guide-sign colour conventions, not the colour scheme of STOP or speed-limit signs. Their selection helps maintain consistency and legibility as travellers move through different roadway environments.

Question 15
ప్రశ్న 15
IRC:67-2022 Table 15.1 gives a normal advance siting range of 110 to 180 m for a warning sign on a road with design speed in the 66–80 km/h band. For a 75 km/h road with no exceptional gradient or visibility constraint, which proposed distance falls within that stated range?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The question supplies the normal advance range applicable to the stated design-speed band. The lower limit is 110 m and the upper limit is 180 m. A proposed placement 150 m in advance lies within those bounds. The alternatives 60, 260 and 400 m fall outside the stated normal range. Final siting must still provide adequate clear visibility and may need adjustment for gradient or other site-specific conditions.

Question 16
ప్రశ్న 16
For a road with design speed 75 km/h, what side length does IRC:67-2022 Table 15.1 specify for the usual upright triangular cautionary or warning sign?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A design speed of 75 km/h falls in the 66–80 km/h band. IRC:67-2022 assigns a triangular warning-sign side length of 900 mm for this band. The figure is a sign dimension, not the distance from the sign to a hazard. Smaller or larger sign sizes correspond to different design-speed ranges. Correct board sizing must be accompanied by legible symbols and appropriate installation position.
వివరణ:
Question 17
ప్రశ్న 17
For the ordinary regulatory sign size schedule in IRC:67-2022 Table 14.4, what diameter applies to a conventional prohibitory sign on a road with design speed 90 km/h?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A road design speed of 90 km/h belongs to the 81–100 km/h band. IRC:67-2022 Table 14.4 specifies 900 mm diameter for the relevant ordinary regulatory signs in that band. The figure applies to the stated circular regulatory-sign size schedule. It should not be confused with the side length of a triangular warning sign. STOP and GIVE WAY have their own dimension tables and should not be sized by assuming every regulatory sign is an ordinary circle.

Question 18
ప్రశ్న 18
A warning sign first becomes legible 160 m before its associated hazard. A vehicle approaches at a constant 72 km/h without braking before reaching the hazard. Neglecting changes in speed, what time is available between first legibility and arrival at the hazard?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The specified speed is 72 km/h, equivalent to 72/3.6 = 20 m/s. The sign becomes legible 160 m before the hazard. At constant speed the time to cover this distance is 160/20. Therefore the available interval is 8 seconds. This calculation does not by itself establish adequacy because driver comprehension, reaction and required manoeuvre time must also be checked.

Question 19
ప్రశ్న 19
A roadside sign on a kerbed city footpath may project into the pedestrian route. What is the minimum underside mounting height required above the kerb for this typical arrangement under the cited IRC:67-2022 siting guidance?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Signs beside pedestrian space must be mounted without creating a headroom hazard. The cited IRC guidance specifies at least 2.1 m above the kerb for the bottom of the lowest sign in the relevant kerbed-road arrangement. This minimum should be considered alongside lateral positioning and accessibility. A 0.6 m lateral offset is not a substitute for vertical pedestrian clearance. Greater overhead clearance rules apply to different installations such as gantry structures.

Question 20
ప్రశ్న 20
A survey finds that a warning sign has been installed facing sharply away from the oncoming traffic stream, reducing its effective visibility. Which installation principle should guide correction under IRC:67-2022?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Sign orientation affects the ability of approaching users to recognise the message in time. The general IRC principle is to position the sign face approximately at right angles to the approaching line of travel. The sign must also be free from sight obstructions and large enough for the operating context. A board seen mainly edge-on can fail even if its material is retroreflective. Site-specific exceptions, such as the orientation of some parking signs, should be handled under their relevant provisions.

Question 21
ప్రశ్న 21
A traffic authority compares ordinary painted sign panels with compliant retroreflective sign sheeting for nighttime visibility under vehicle headlights. Which explanation correctly describes retroreflection?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Retroreflective materials return incident light largely towards its source direction. Vehicle headlights illuminate the sign and some of that light returns towards the approaching vehicle. This improves nighttime visibility without requiring the sign itself to be electrically illuminated. Performance depends on sheeting type, geometry, cleanliness and material condition. Retroreflection does not alter the legal category or intended meaning of a sign.
వివరణ:
Question 22
ప్రశ్న 22
An installed curve-warning sign has sound retroreflective sheeting but is hidden behind roadside vegetation for most approaching drivers. Which engineering action is most appropriate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A road sign can perform its function only when approaching road users can see and understand it in time. Vegetation that hides the face defeats that requirement even if the sheeting remains effective. The obstruction should be cleared or the sign position corrected using appropriate siting criteria. Its visibility should then be checked in relevant day and night conditions. Maintenance must also address faded, damaged or poorly oriented signs rather than focusing on reflectivity alone.

Question 23
ప్రశ్న 23
Several outdated and duplicate signs accumulate before an urban interchange, making the current exit direction difficult to identify. Which management action best follows sound traffic-signing principles?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Signs should communicate relevant information with adequate time for driver response. Excess or conflicting signs can create visual clutter and reduce comprehension. An inventory review should identify boards that are obsolete, duplicative or inconsistent with the current road layout. Necessary signs should be positioned and ordered to match the actual decisions drivers face. A sound panel should not remain in use when its message is no longer appropriate.

Question 24
ప్రశ్న 24
A multilane urban flyover approach has separate lanes for straight-through movement and an exit serving multiple destinations. Drivers frequently change lanes late because they do not know the lane allocation. Which signing treatment best addresses this deficiency?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Complex junctions benefit from direction information that matches the lane choices drivers must make. Advance lane-specific signing gives drivers time to select the correct movement. An overhead installation may improve association between a direction legend and a particular lane. The boards must use the relevant guide-sign conventions and have adequate visibility and legibility. They do not replace any necessary regulatory lane-control or hazard-warning signs.

Question 25
ప్రశ్న 25
A city is preparing an integrated signing plan for a school-side urban intersection where vehicles must not turn right, pedestrians cross near the school, and drivers need advance directions to an authorised alternative route. Which package is most defensible?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The intersection presents distinct regulatory, warning and navigation needs. A regulatory sign is required to communicate the prohibited right-turn manoeuvre. Suitable warning and crossing-related signing addresses the school and pedestrian context. Advance direction information helps drivers identify an authorised alternative without last-moment manoeuvres. The package must be checked against actual pedestrian demand, traffic control, approach speed and applicable sign-placement requirements.
