Final answer:
On a road covered with loose gravel, slowing down and avoiding sudden actions is crucial for safety to prevent skidding or losing control of the vehicle.
Step-by-step explanation:
When driving on a road covered with loose gravel, the safest action to take is to slow down and avoid sudden braking or making sharp turns. Braking suddenly on gravel can cause a vehicle to skid due to the reduced traction, and sharp turns can make the vehicle slide or lose control entirely, increasing the risk of an accident.
This is because the loose gravel reduces the traction between the tires and the road, making it easier for the car to skid or lose control. By slowing down and driving with caution, you can maintain better control of the car and reduce the risk of accidents.
