25. The best way to avoid hydroplaning is to:

Keep your tires properly maintained.

Slow down when roads are wet or slushy.

Watch out for standing water or puddles.

All of the above.

When roads are wet, cars take a longer distance to stop and may skid on quick turns. Do not use cruise control when driving under wet or icy conditions. Reduce your speed and drive with caution.

26. Roads become very slippery:

When it has been raining for an hour or more.

The day after it rains.

For the first 10 to 15 minutes of a rainstorm.

Right after the rain has stopped.

Pavement can become very slippery within the first 10 to 15 minutes of a rainstorm because the rain causes oil in the asphalt to rise to the surface of the road. This problem becomes even worse in hot weather. The heat combined with the water causes more oil to rise to the road surface.

27. When driving on wet pavement, it's important to remember:

That pavement is especially slippery right after it starts to rain.

That wet roads can cause hydroplaning.

To give yourself additional space when coming to a stop.

All of the above.

Wet roadway surfaces can be dangerously slick, especially immediately following a rainfall. When you are driving on wet roads, your vehicle is traveling on a thin layer of oil, dirt, and water. Slow down when there is heavy rain, standing water, or slush on the road to reduce the risk of your wheels losing traction on the slick surface.

28. How can you lower the risk of hydroplaning?

Do not speed when the roads are wet.

Use tires with proper air pressure.

Replace tires with bad tread.

All of the above.

Hydroplaning happens when a vehicle glides on top of a thin layer of water between its tires and the road. Tires with low air pressure or bad tread can increase the risk of hydroplaning. Speeding also increases the risk.

29. Traffic signs and pavement markings:

Must always be obeyed.

Are merely suggestions.

Must be followed only when there is other traffic.

Must be followed only when a police officer is present.

Traffic flow is controlled by pavement markings, traffic islands, signals, and signs. These devices inform drivers of conditions on the roadway and help guide drivers safely to their destinations. You must always obey traffic signs, signals, and pavement markings.

30. You can help keep the driver behind you a safe distance away from your vehicle by:

Driving 10 mph faster than the car behind you.

Driving 10 mph slower than the car behind you.

Maintaining a steady speed.

It is not always easy to maintain a safe distance behind your vehicle. However, you can help keep the driver behind you a safe distance away from your vehicle by maintaining a steady speed and signaling turns, lane changes, and deceleration in advance.
