Study guide, answers and sources

This study material shows answers before an attempt is finished.

The brake item concerns the stated no-ABS skid and sinking-pedal condition. Accelerator guidance comes from a DMV teen-driver guide; its use for adult Class C supplemental study is a bounded independent reviewer inference, and the full handbook PDF reviewed did not contain that procedure.

On a steep, narrow mountain road, your car and an oncoming car meet at a point where neither can pass. You are traveling downhill; the other driver is traveling uphill. Under the California handbook rule, what should happen?

The uphill driver has the right-of-way; the downhill driver should back up the hill until the uphill driver can pass. (correct): Correct. This applies the handbook’s specific rule for two vehicles meeting on a steep narrow road when neither can pass.
The downhill driver has the right-of-way because it is easier to keep moving downhill.: Incorrect. The handbook assigns right-of-way to the uphill vehicle; it does not give priority to the downhill vehicle.
The driver in the larger vehicle has the right-of-way, regardless of direction.: Incorrect. Vehicle size is not the criterion in the handbook rule; direction on the specified steep narrow road controls.

The handbook gives the uphill vehicle the right-of-way when two vehicles meet on a steep narrow road and cannot pass. It says the downhill vehicle should back up the hill until the uphill vehicle can pass. The scenario includes both required conditions: steep and narrow, with no room to pass.

As you brake on a California road, the car begins to skid and the pedal sinks to the floor. Your car has no ABS. Which immediate action matches the California Driver's Handbook guidance for this condition?

Quickly pump the pedal by gently applying and releasing pressure. (correct): Correct. This is the handbook's stated response for a sinking pedal in the no-ABS context described here.
Hold the pedal down continuously and switch off the ignition while the car is moving.: Incorrect. The cited guidance calls for pumping in this case; switching off while moving is not the recommended action and can affect steering in some vehicles.
Pump the accelerator and brake together to dry the brakes.: Incorrect. Pressing the accelerator and brake together is described for drying wet brakes, a different condition.

For the described no-ABS skid, the handbook says that when the pedal sinks to the floor, quickly pump the brakes by gently applying and releasing pedal pressure. Its nearby separate instruction about wet brakes is not the response to a sinking pedal. This item does not generalize the pumping advice to every ABS type or every braking problem.

California Driver's Handbook — Section 8: Safe Driving — Locked Wheel Skids, paragraph beginning 'If your vehicle is not equipped with ABS and begins to skid'; bullet for brake pedal sinking to floor; adjacent downshift/emergency-brake guidance. Current rendered page lines 168-182.

You are driving slowly on a two-lane mountain road. Passing is unsafe, and five vehicles are following you. A marked turnout is available ahead. What does the California handbook require?

Use the turnout to let the vehicles behind you pass. (correct): Correct. The road has two lanes, you are driving slowly, passing is unsafe, and five vehicles are following.
Stay in the travel lane until there are at least six vehicles behind you.: Incorrect. The stated threshold is five or more vehicles, so six are not required.
Use the turnout only if a driver behind you honks.: Incorrect. A horn is not one of the stated conditions. The stated traffic and road conditions trigger the rule.

The handbook says a driver must use a turnout area or lane when driving slowly on a two-lane road, where passing is unsafe, and five or more vehicles are following. All those conditions are stated here.

While driving through a commercial street, the accelerator pedal stays down and the car continues to gain speed. What should the driver do first according to California DMV emergency guidance?

Shift the transmission into neutral, then continue controlling the vehicle. (correct): Correct for the DMV procedure being taught: select neutral first, then keep attention on steering, braking, and the road.
Turn the ignition off immediately, before changing direction or stopping.: Incorrect. The guide says to turn off the ignition only once the vehicle has stopped and the driver no longer needs to change direction.
Look down and reach toward the pedal to free it while moving.: Incorrect. The guide emphasizes keeping eyes on the road; reaching toward the pedal while moving is not its recommended response.

The California DMV emergency guide lists shifting into neutral first, followed by braking while keeping eyes on the road and finding a safe way out of traffic. This is general emergency guidance in a teen-driver guide; the current full handbook PDF reviewed for this pack did not contain a stuck-accelerator procedure, so adult Class C applicability and currency need independent review.

You are driving slowly on a two-lane mountain road where passing is unsafe. Four vehicles are following you, and a turnout is available. Based on the handbook’s stated mandatory-use rule, which statement is accurate?

The five-or-more-vehicles condition is not met, so this specific rule does not yet require you to use the turnout. (correct): Correct. The rule’s five-or-more threshold is not met. This is limited to the handbook’s stated mandatory-use condition.
You must use the turnout because any vehicle following on a two-lane road makes it mandatory.: Incorrect. The specific must-use rule requires five or more following vehicles, not simply one or more.
You must use the turnout because passing is unsafe, even without the required number of following vehicles.: Incorrect. Unsafe passing is one required condition, but the rule also requires slow driving on a two-lane road and five or more vehicles following.

The handbook’s specific must-use rule applies when a driver is going slowly on a two-lane road, passing is unsafe, and five or more vehicles are following. Four does not meet the stated numerical threshold. This answer addresses only that specific mandatory-use rule; it does not claim that other rules or conditions never apply, and the handbook separately describes turnouts as a way to let vehicles behind pass.

California Driver’s Handbook, Section 6: Navigating the Roads — Section 6 → Turnout Areas or Lanes; general description at lines 160–162; mandatory-use conditions at lines 166.

After selecting neutral for a stuck accelerator, a driver is still rolling along a busy avenue. Which response best follows California DMV guidance?

Keep eyes on the road, brake, look for a way out of traffic, warn others with the horn and emergency lights, and guide the car safely off the road. (correct): Correct. It preserves road attention, braking, traffic awareness, warning, and a safe exit from traffic.
Focus on the dashboard, avoid braking, and wait for the car to stop in its lane.: Incorrect. It conflicts with the guide's directions to brake, watch the road, and look for a safe way out of traffic.
Turn off the ignition while rolling, then steer without checking the road.: Incorrect. The guide warns against turning off the ignition until the vehicle has stopped, because steering may lock on some vehicles.

The DMV guide's sequence after selecting neutral includes applying the brakes, keeping eyes on the road, looking for a way out of traffic, warning other drivers, and trying to drive safely off the road. The choices combine these closely related actions into one scenario decision; they do not add a repair step.

At a blind bend on a narrow mountain road, you can see only about 150 feet of roadway ahead. Which horn use matches California handbook guidance?

Sound it to alert oncoming traffic before entering the limited-visibility section. (correct): Correct. The narrow mountain road and approximately 150-foot sight distance meet the handbook’s condition for alerting oncoming traffic.
Do not use it; horns are only for warning pedestrians.: Incorrect. The handbook also says a horn can warn other drivers or hazards and specifically includes this mountain-road use.
Use it only after you see an oncoming vehicle.: Incorrect. The purpose is to alert oncoming traffic when visibility is limited; waiting until you see a vehicle would not apply that guidance.

The handbook lists alerting oncoming traffic on a narrow mountain road where sight distance is below 200 feet as a use of the horn. The view described here is about 150 feet.

California Driver’s Handbook, Section 5: An Introduction to Driving — Section 5 → Signals, Horns, and Headlights → Using Your Horn; lines 129–135.

A driver has guided a car with a stuck accelerator completely off a busy road and brought it to a stop. The driver no longer needs to change direction. When does the DMV guide say to turn off the ignition?

Now that the vehicle is stopped and no direction change is needed. (correct): Correct. Both conditions in the prompt match the guide's stated timing: stopped and no longer needing to change direction.
As soon as the accelerator sticks, even if the car is still moving.: Incorrect. The guide expressly says not to turn off the ignition before a complete stop.
Before steering off the road, so the engine cannot run.: Incorrect. Steering off the road may still be needed; the guide places shutoff after stopping and completing direction changes.

The DMV guide places ignition shutoff after the vehicle has stopped and the driver no longer needs to change direction. It warns that turning off the key can lock steering on many vehicles, so this is not an in-motion step.
