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

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.

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.

California DMV Teen Driver Tips — Handling Special Problems & Emergencies — Handling Special Problems & Emergencies, 'What should I do if my accelerator gets stuck?', lines 195-203 in current rendered page.

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.

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.
