Special Driving Conditions Flashcards

When driving on a mountain road in California, what is the recommended technique for descending a steep grade?

Answer: Shift to a lower gear and use engine braking, applying brakes as needed

Engine braking in a lower gear controls speed on steep descents without overheating brakes, which can fade if used continuously.

In California, when must you chain up your tires on mountain roads?

Answer: When Caltrans posts R-2 or R-3 chain control requirements for your vehicle class

Caltrans uses a numbered system (R-1, R-2, R-3) to post chain requirements — you must comply with requirements posted for your vehicle class.

When driving in desert heat in California, which precaution helps prevent vehicle overheating?

Answer: Reduce speed and watch the temperature gauge closely

Reducing speed lowers engine workload in extreme heat, and monitoring the temperature gauge helps you catch overheating before damage occurs.

When your vehicle overheats on a California highway, you should:

Answer: Pull over safely, turn off the engine, and let it cool before adding coolant

You must let an overheated engine cool completely before opening the radiator — the pressurized steam can cause severe burns.

Night driving is more dangerous than daytime driving primarily because:

Answer: Visibility is significantly reduced, limiting reaction time

Reduced visibility at night shortens the distance you can see hazards, giving you less time to react compared to daylight driving.

When driving in a construction zone in California, you should:

Answer: Increase following distance and reduce speed

Construction zones have workers and equipment near traffic — reducing speed and increasing following distance gives you time to react to sudden changes.
