California driver's examination

Even when you signal, you should not assume that the space you want to occupy is free or that other drivers will give you the right of way.

Signal at least five seconds prior to a changing lanes on a freeway. Always signal when turning left or right, changing lanes, slowing down, or stopping to let other drivers, motorcyclists, bicyclists, and pedestrians know your intentions.

To prevent hydroplaning, maintain your tires in good condition, and lower your speed in response to wet roads. If you detect a loss of control, take your foot off the gas, do not apply the brakes, maintain the direction of the vehicle, and allow the vehicle to slow to a manageable speed.

On most California highways, the basic speed limit is 65 mph. You may drive at 70 mph if that limit is posted.

For drivers age 21 or older, it is illegal to drive with a blood alcohol content (BAC) of 0.08% or more (or 0.04% or more for commercial vehicle drivers). For drivers under age 21, it is illegal to drive with a BAC of 0.01% or more

Slow-moving vehicles, such as farm tractors, road maintenance vehicles, and animal-drawn carts, display an orange and red triangle on the back.

You may sometimes turn right when stopped by a solid red light. You may never turn left or right when stopped by a traffic light with a red arrow.

If you are in an intersection when you see an emergency vehicle using its flashing lights and/or sirens, continue through the intersection and then drive to the right as soon as it is safe and stop. You must yield the right-of-way to any police vehicle, fire engine, ambulance, or other emergency vehicle using a siren and red lights.

To avoid last minute moves, scan the road 10–15 seconds ahead of your vehicle so you can see hazards early. Constantly staring at the road right in front of your vehicle is dangerous. As you scan ahead, be alert for vehicles around you.
