Accepted Answer

Option A: Attract disqualification of driving license. Smoking while driving a public service passenger vehicle violates conduct rules and can lead to suspension or disqualification of the driver's driving license.

Question 50

Driving a four wheeler on a wet road is difficult due to

Accepted Answer

Option A: Decrease the friction between tyre and road surface. Water on road surfaces forms a thin lubricating liquid film that substantially decreases the coefficient of friction and grip between tyre rubber and pavement, increasing stopping distance and risk of hydroplaning.

Question 51

The most preferable driving technique with wet roads is

Accepted Answer

Option B: Change down gear and reduce speed. On wet or slippery roads, downshifting to a lower gear and reducing speed allows engine braking and maximizes tyre grip while minimizing reliance on sudden wheel-locking brakes.

Question 52

Consider the following statements:
Statement-1: In case of skidding, distance traveled along the road is more than the movement of wheel circumference.
Statement-2: In case of slipping, distance traveled along the road is less than the movement of wheel circumference.
Choose the correct combination:

Accepted Answer

Option A: Both statement (1) and statement (2) are individually true.. In highway engineering: Skidding occurs when wheels slide without full rotation (path length $>$ circumferential rotation); Slipping/Spinning occurs when wheels spin in place on low traction surfaces (path length $<$ circumferential rotation). Both statements are true.

Question 53

Sudden application of brakes on a wet road and improper super elevation may cause

Accepted Answer

Option B: Skidding. Sudden heavy braking on low-friction wet surfaces when lateral forces exceed tyre traction creates severe directional loss of control known as Skidding.

Question 54

When driving at night in rainy or foggy conditions, high beams is

Accepted Answer

Option A: Bad as it increases glare and limits driver vision. Using high beams in rain or fog is dangerous because water droplets reflect light directly back into the driver's eyes (backscatter reflection/glare), blinding the driver.

Question 55

Yellow colour light is most preferred over white colour as a fog light because

Accepted Answer

Option C: Yellow light has larger wavelength than white light and is conspicuous with less scattering. Yellow light possesses a longer wavelength than blue/violet components of white light. By Rayleigh's scattering law ($I \propto 1/\lambda^4$), longer wavelengths undergo less forward scatter and produce less blinding glare in fog.

Question 56

Arrange the following coloured lights in shortest to longest wavelength:
(i) Green
(ii) Yellow
(iii) Orange
(iv) Red

Accepted Answer

Option A: (i) (ii) (iii) (iv). Visible spectrum wavelengths increase in the sequence VIBGYOR: Green ($sim 520	ext{ nm}$, i) → Yellow ($sim 580	ext{ nm}$, ii) → Orange ($sim 600	ext{ nm}$, iii) → Red ($sim 700	ext{ nm}$, iv) $\implies$ (i) (ii) (iii) (iv).

Question 57

On a foggy day, two bus drivers spot each other traveling at $20	ext{ m/sec}$ and $10	ext{ m/sec}$ towards each other. Both apply brakes decelerating at $5	ext{ m/s}^2$. What is the total combined distance covered by both buses before coming to a stop?

Accepted Answer

Option B: 50 meter. Stopping distance formula $s = \frac{v^2}{2a}$:
- For Bus 1: $s_1 = \frac{20^2}{2(5)} = \frac{400}{10} = 40	ext{ m}$
- For Bus 2: $s_2 = \frac{10^2}{2(5)} = \frac{100}{10} = 10	ext{ m}$
Total combined stopping distance required $= 40 + 10 = 50	ext{ meters}$.

Question 58

A high beam in foggy conditions is

Accepted Answer

Option A: Bad because it reflects back and can dazzle. High beams in dense fog reflect off airborne water droplets directly back into the driver's eyes, creating a wall of white glare that blinds the driver.

Question 59

When you are driving at night and approaching another vehicle from behind, you must

Accepted Answer

Option B: Use low beam or dim your headlights. When following another vehicle within 200 meters at night, drivers must switch to low beam (dim headlights) to prevent blinding the leading driver through their rearview mirrors.

Question 60

When you are driving at night and want to overtake a car in front, you must

Accepted Answer

Option A: Flash your headlamps before overtaking. Flashing headlamps (headlight flasher / optical horn) at night alerts the driver ahead of your intention to overtake without causing prolonged dangerous glare.

Question 61

Arrange the following steps in correct sequence when a motor vehicle breaks down at night:
(i) Apply brakes
(ii) Slow down the vehicle
(iii) Turn on hazard warning lights
(iv) Get out from the vehicle safely

Accepted Answer

Option B: (ii) (i) (iii) (iv). Safe breakdown sequence: (ii) Gently slow down vehicle → (i) Steer off roadway and apply parking brakes → (iii) Turn on hazard warning flashers → (iv) Exit vehicle safely on passenger side $\implies$ (ii), (i), (iii), (iv).

Question 62

To see a vehicle in the blind spots, a driver should

Accepted Answer

Option C: Turn his/her head (shoulder check). Because mirrors cannot cover the blind spot adjacent to the rear B/C pillars, a driver must perform a physical head turn (shoulder check) before changing lanes.

Question 63

Which of the following is recommended while driving at night on a low-lit street?

Accepted Answer

Option A: Drive slowly and use headlights. On poorly illuminated streets at night, drivers should reduce vehicle speed to match stopping sight distance and use properly aligned headlights.

Question 64

During night driving, which type of pavement provides greater visibility?

Accepted Answer

Option C: Concrete pavement. White/light-grey Cement Concrete pavement has a much higher albedo and diffuse reflectance than dark black bituminous asphalt, providing superior night-time contrast and visibility.
