While driving on a rural road, your right wheels run off the pavement. You should hold the steering wheel firmly andA: Immediately steer left, back toward the paved surface of the road.B: Steer to the right, toward the shoulder or ditch.C: Steer in a straight line while gently slowing down.

Answers

Answer:

The answer is C. Steer in a straight line while gently slowing down

Explanation:

The following are advised when your cars go off the pavement while driving;

firstly, Do not panic.

ensure you hold on to your steering wheel tightly.

keep Steering straight ahead.

ensure you Stay on the shoulder.

Ease up on the accelerator and brake gently.

When you know you can safely do so, turn back on the road at a much lower speed.

Final answer:

When the right wheels run off the pavement while driving, you should hold the steering wheel firmly, continue driving straight, and slowly reduce your speed. This avoids the dangers of immediately steering back onto the road or towards the shoulder.

Explanation:

While driving on a rural road, if your right wheels run off the pavement, the safe response would be to hold the steering wheel firmly and steer in a straight line while gently slowing down. Immediately steering back towards the paved surface (option A) can cause your vehicle to roll or veer into oncoming traffic. Steering towards the shoulder or ditch (option B) risks hitting obstacles or further losing control. By continuing straight at a controlled, reduced speed, you can safely return to the pavement when there's a break in the roadside or ample space to move back onto the road.
