Subject to the speed limit; what is the ?safest? speed to drive at?

Correct Answer

The speed that will enable the driver to stop the vehicle within the distance ahead that they can see to be clear.

Explanation: You should always drive at a speed that allows you to stop within the distance that you can see to be clear ahead. If you don't think you could safely bring the vehicle to a stop within the range of what you can see; then you're driving too fast ? slow down.
