Explanation: Section 134 of the Motor Vehicles Act explicitly mandates that if a driver is involved in an accident resulting in injury, their primary legal duty is to take all reasonable steps to secure medical attention for the injured person and report the accident to the nearest police station within 24 hours.

Solution 140: Option C (To dampen the rebound of the suspension springs and keep tyres in contact with the road)

Explanation: While the suspension springs absorb the impact of bumps, they will continue to bounce (oscillate). The shock absorber's mechanical purpose is to dampen or control this bounce, ensuring the tyre remains in constant contact with the road for safe steering and braking.

Solution 141: Option C (To allow the drive wheels to turn at different speeds when cornering)

Explanation: When a vehicle takes a turn, the outside wheel travels a longer distance than the inside wheel. The differential is a gear mechanism in the drivetrain that splits engine torque and allows these wheels to rotate at different speeds, preventing tyre scrubbing and axle stress.

Solution 142: Option B (Distilled water contains no impurities or minerals that can damage the internal battery plates)

Explanation: Normal tap water contains minerals and ions (like calcium and iron) that will react with the sulfuric acid in a lead-acid battery, coating the lead plates and drastically shortening the battery's life. Distilled water is pure H2O and prevents this internal damage.

Solution 143: Option C (Power or Combustion stroke)

Explanation: The standard operating cycle of a 4-stroke engine follows this sequence: 1. Intake (draws fuel/air), 2. Compression (compresses the mixture), 3. Power/Combustion (spark plug ignites mixture, forcing piston down), 4. Exhaust (expels burnt gases).

Solution 144: Option C (Hydroplaning or Aquaplaning)

Explanation: Hydroplaning occurs when water on the road accumulates in front of the vehicle's tyres faster than their treads can displace it. The tyre is pushed up onto a thin layer of water, completely losing contact with the road and resulting in a total loss of steering and braking control.

Solution 145: Option B (To prevent severe whiplash injury to the neck in a rear-end collision)

Explanation: While they provide comfort, headrests (or head restraints) are primarily critical safety devices. In a rear-end collision, the body is thrown forward, but the head snaps backward violently. A properly adjusted headrest catches the head, preventing severe whiplash injuries to the cervical spine.

Solution 146: Option C (Shifting to a lower gear to slow down the vehicle using engine resistance without applying the foot brake)

Explanation: Engine braking is a technique, particularly useful on long downhill descents, where a driver shifts to a lower gear. The internal resistance (compression) of the engine slows the vehicle's momentum naturally, preventing the main wheel brakes from overheating and failing.

Solution 147: Option B (Only when visibility is severely reduced by dense fog, heavy rain, or falling snow)

Explanation: Fog lights project a wide, low, and extremely bright beam designed to cut beneath fog or heavy rain to illuminate the immediate road surface. Using them in clear conditions is illegal and dangerous as their intense brightness dazzles oncoming drivers.

Solution 148: Option C (Slam hard on the brakes)

Explanation: In the event of a high-speed blowout, the vehicle will pull violently to one side. Slamming the brakes causes an abrupt shift in weight and will instantly throw the car into an uncontrollable spin. The driver should firmly grip the wheel, ease off the accelerator, and brake gently only after gaining control.

Solution 149: Option B (It completely eliminates the safe stopping distance required if the front vehicle brakes suddenly)

Explanation: Tailgating means driving too closely behind the vehicle in front. Human reaction time combined with mechanical braking time dictates a minimum safe stopping distance. Tailgating eliminates this distance, making a severe rear-end collision virtually unavoidable if the leading vehicle stops abruptly.

Solution 150: Option C (Stop the vehicle, look both ways, and listen to ensure no train is approaching)

Explanation: At an unmanned or unguarded railway crossing, the absolute legal and life-saving duty of a driver is to bring the vehicle to a complete halt, look in both directions, and listen carefully for train horns before proceeding across the tracks.
