The correct answer is: A. Stopping sight distance is always less than overtaking sight distance.
Stopping sight distance is the distance required to stop a vehicle after the driver sees a hazard. Overtaking sight distance is the distance required to overtake another vehicle safely.
Stopping sight distance is always less than overtaking sight distance because the driver must first react to the hazard before applying the brakes. This reaction time adds to the distance required to stop the vehicle.
The following are some factors that affect stopping sight distance:
- The speed of the vehicle. The faster the vehicle is traveling, the longer it will take to stop.
- The condition of the road surface. A wet or icy road will require more stopping distance than a dry road.
- The type of vehicle. A heavier vehicle will require more stopping distance than a lighter vehicle.
- The driver’s reaction time. A driver with a slower reaction time will require more stopping distance than a driver with a faster reaction time.
It is important to be aware of the stopping sight distance required for your vehicle and to drive accordingly. Always leave enough space between you and the vehicle in front of you so that you can stop safely if necessary.
