Final answer:
To maintain control when stopping on snow-covered roads without ABS, use threshold braking or pump the brakes, brake gently, increase following distance, and start braking early. Factors like speed, vehicle weight, and tire condition affect stopping distance.
Step-by-step explanation:
When stopping on snow-covered roads in a vehicle without an Anti-lock Braking System (ABS), it is essential to use certain techniques to maintain control and ensure safety. One recommended technique is 'threshold braking' which involves applying the brakes up to the point just before the wheels lock, then easing up slightly on the brake pedal, before reapplying with the same pressure. This method helps in maintaining steering control while maximizing braking efficiency. Another approach is 'pumping the brakes', which means repeatedly pressing and releasing the brake pedal to prevent the wheels from locking. It is crucial to start braking early and to increase the distance from the vehicle in front since stopping distances can be much greater on snow or ice. Also, keep in mind that braking gently and progressively is key, sudden movements can lead to loss of traction and subsequent loss of control.
The stopping distance on snow or ice can be affected by factors such as speed, the vehicle's weight, tire conditions, and the driver's reaction time. Hence, it's vital to adjust your driving according to the conditions.
