During the on-road driving skills test, you may be asked to drive on an expressway. Make sure you maintain proper lane positioning, vehicle spacing, and vehicle speed. Continue to thoroughly check traffic in all directions while on the expressway.

2. When approaching your vehicle as part of your pre-trip inspection, you should look for what as a sign of trouble?

When approaching your vehicle for an inspection, you should look underneath the vehicle for fresh leaks of oil, coolant, grease, or fuel. Seeing a fresh puddle of any of these fluids could indicate a safety issue with your vehicle.

3. A cardboard box on the roadway:

Almost any foreign object on the road poses some potential danger. For example, even something as seemingly harmless as a cardboard box could contain a hard or heavy object that could damage your vehicle.

4. How much water must be on a road surface for a vehicle to hydroplane?

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.

5. To prevent fatigue while driving, you should:

A hot, poorly-ventilated area can make a person sleepy. Opening a window, opening a vent, or using the air conditioning can help keep the cab cool and reduce the risk of fatigue.

6. During a pre-trip inspection, what is the best method for checking your lights?

During a pre-trip inspection, you should activate your lights, then get out of the vehicle to look at them.

7. On a passenger bus, carry-on baggage:

Bus passengers should not be allowed to leave baggage in any doorway or aisle. Baggage and freight must be secured in a manner that will prevent damage, allow the driver to move freely and easily, allow riders to exit by any window or door in an emergency, and protect riders from injury if the items fall or shift.
