Final answer:
The CDL Guide recommends maintaining a following distance of four to six seconds on slippery roads.
Step-by-step explanation:
The Commercial Driver's License (CDL) Guide advises drivers to maintain a safe following distance, especially on slippery roads. The recommended space that should be kept ahead of a truck depends on various factors such as speed, road conditions, and visibility. However, a general guideline is to maintain a following distance of at least four to six seconds from the vehicle in front of the truck.
In wet weather, stopping distances will be at least double those required for stopping on dry roads (see rule 126). This is because your tyres have less grip on the road. In wet weather: you should keep well back from the vehicle in front - this will increase your ability to see and plan ahead.
This diamond-shaped sign features an icon of a car with two swerving lines underneath which represent the car possible losing control due to slick conditions. This sign is put in place to warn drivers when there may be some slippery, slick conditions ahead.
