15 . You should always be able to stop within:
A minute of hitting the brakes.

16 . How much water is needed on a road surface for a vehicle to hydroplane?
No water
Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be much water on the road for this to occur.

Drive faster than the posted speed limit.
While driving, you should continually scan the road to spot potential hazards in advance. Make emergency plans for how to deal with the hazards if they become dangerous.

Placards must be placed on the front, the rear, and both sides of a vehicle carrying hazardous cargo. They must be readable from any direction.
19 . Looking far ahead of your vehicle while driving is:
Only encouraged if you are transporting hazardous materials.
Good drivers look down the road at least 12 to 15 seconds ahead of their vehicles. This makes it possible to identify hazards early, when drivers are more likely to have time to respond appropriately.

Turn off all lights.
If you must stop on the side of the road, it is important that you turn on your emergency flashers as a warning to other drivers. This is especially important if you are stopped at night.
