High winds — California Permit Test
High winds on the California permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
High winds are a hazard while driving, especially for larger vehicles such as trucks, campers and vehicles with trailers, so reduce your speed for better control.
A gust pushes on the side of the car, and the faster you are going the less time you have.
High winds can be a hazard while driving. This is especially true for larger vehicles such as trucks, campers, and vehicles with trailers.
In high winds, maintain a firm hand position on the steering wheel, because strong gusts are unpredictable and you can lose control if you are not holding the wheel properly.
A gust arrives without warning, and a loose grip means the wheel moves before you do.
Maintain a firm hand position on the steering wheel. Strong wind gusts are unpredictable.
Do not use cruise control in high winds, so you keep maximum control of the accelerator if a gust occurs.
Cruise control keeps the speed up exactly when you would want to ease off.
Do not use cruise control. Maintain maximum control of the accelerator if a gust occurs.
On the test
Which vehicles are most affected by high winds?
Trucks, campers and trailers. A gust pushes on the side of the car, and the faster you are going the less time you have. California Driver’s Handbook, p.63: “High winds can be a hazard while driving. This is especially true for larger vehicles such as trucks, campers, and vehicles with trailers.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
