25. You should increase the distance between your vehicle and the vehicle ahead when you:

Are following a small passenger vehicle.

Are being tailgated by another driver.

Are driving more slowly than the posted speed limit.

When being tailgated, create extra space in front of your vehicle and do not brake suddenly. Slow down gradually or merge into another lane to prevent a collision with the tailgater.

26. Construction zone signs are generally:

Square or rectangular with white and red coloring.

Round or octagonal with black and yellow coloring.

Diamond-shaped or rectangular with orange and black coloring.

All temporary signs in work zones have an orange background with black letters or symbols. These signs are found on the right side of the road, or on both the left and right sides if the roadway is a divided highway.

27. It is best to keep a space cushion:

Only in back of your vehicle.

Only on the left and right sides of your vehicle.

Only in front of the vehicle.

On all sides of the vehicle.

To ensure that you will have time to react to hazards on the roadway, it is best to keep a cushion of space on all sides of your vehicle. Do not crowd vehicles to your left and right sides.

28. You are approaching an intersection at the posted speed limit when the signal turns yellow. You should:

Slow down and proceed through the intersection without caution.

Speed up to cross the intersection before the light turns red.

Stop before entering the intersection, if you can do so safely.

A solid yellow light means "caution" and signals that the light will soon turn red. You should stop at a solid yellow light if you can do so safely; otherwise, you should cautiously cross the intersection.

29. At a light rail intersection, always:

Look both ways before crossing tracks.

Pay attention and obey all traffic signals.

Share the road with pedestrians and bicyclists.

All of these.

You should never drive around lowered crossing gates. Always look both ways before turning across train tracks and always obey signs and traffic signals. Trains share the road with motor vehicles and bicyclists.

30. What may help drivers conserve gasoline?

Sitting in their driveways with their cars running.

Accelerating quickly.

Slowing down gradually.

Braking abruptly.

Every time you have to stop quickly, it takes time and fuel to accelerate and get your vehicle back up to the speed of traffic. Drivers who look far ahead of their vehicles can slow down gradually or change lanes to avoid unnecessary braking, leading to better gas mileage.
