Your turn signals fail during a trip. What does the handbook direct while you arrange repair?
Correct answer: Use proper hand signals until the signals can be repaired.
The handbook recognizes hand signals when electric directional signals fail. Repair the defect; a failed lamp does not remove the duty to communicate.

After the parking brake is released, the brake warning lamp comes on when you press the foot brake. What does the handbook say?
Correct answer: The brake system is defective and the vehicle should not be driven.
A warning under these conditions indicates a brake defect requiring attention, not a normal signal to disregard.

In an ordinary modern car with a seat belt for every occupant and no applicable exemption, who must be restrained?
Correct answer: The driver and passengers in both front and rear seats.
The statewide belt law covers the driver and front- and rear-seat passengers, with child restraints required where applicable. A rear seat does not remove the ordinary belt requirement.

You are transporting an 18-month-old in an ordinary passenger car. What restraint does Hawaii law require?
Correct answer: A properly used rear-facing child restraint with a harness meeting federal standards.
A child under two must be properly restrained in a rear-facing harness system. Use an appropriate seat according to its instructions.

What restraint category does Hawaii require for a 3-year-old in an ordinary passenger car?
Correct answer: A rear-facing or forward-facing child restraint with a harness meeting federal standards.
From age two to under four, the law requires a harness restraint, rear- or forward-facing. Follow the seat's fit and installation requirements.

A 6-year-old is tall enough that an adult belt appears to fit. Does height alone qualify this child for Hawaii's statutory belt-only exception?
Correct answer: No; a child of that age still needs a harness restraint or booster meeting federal standards.
The height-based belt exception begins at age seven, not six. Children age four to under ten otherwise need the specified harness restraint or booster.

Which child meets the age and height conditions for Hawaii's belt-only exception when correctly restrained by a lap-and-shoulder belt?
Correct answer: An 8-year-old who is 4 feet 10 inches tall.
The exception requires age seven to under ten and height over four feet nine inches, with a correctly used lap-and-shoulder belt. Both age and height conditions matter.

A trailer blocks the view through your car's inside rearview mirror. What equipment does the handbook require?
Correct answer: Suitable outside rearview mirrors on both sides.
When a trailer obstructs the inside view, proper outside mirrors on both sides provide the needed rearward view.

Before towing a utility trailer, what should you check about its cargo?
Correct answer: The load is secured, properly balanced and not overloaded.
Secure the load and balance it properly. Too little hitch weight can cause fishtailing, while too much can impair steering.

Which nighttime period does Hawaii's statewide headlamp statute specify for a motor vehicle moving on a public highway?
Correct answer: From 30 minutes after sunset until 30 minutes before sunrise.
The statute states this required nighttime interval. Safety guidance also calls for headlights in poor visibility and at dawn or dusk; do not treat the legal interval as a reason to remain unlit when visibility is poor.

After a vehicle passes its official safety inspection, what should be done with the issued inspection certificate?
Correct answer: Keep it in the vehicle.
The handbook says the inspection certificate must remain in the vehicle. A sticker does not eliminate the certificate requirement described there.

You have an opened alcoholic beverage container in the area of an ordinary car occupied by the driver and passengers while on a public road. Is that storage allowed?
Correct answer: No; storing the opened container in that occupied area is prohibited.
The handbook prohibits storing an opened alcoholic beverage container in the area normally occupied by the driver or passengers. A replaced cap or an adult passenger does not resolve that situation.

Your car has antilock brakes and you need an emergency stop. Which habit should you avoid?
Correct answer: Pumping the brake pedal as though the car had no ABS.
The handbook specifically advises practicing not pumping ABS and following the vehicle guidance. ABS manages wheel lockup; do not substitute a non-ABS pumping technique.

An overhead lane-control signal displays a flashing yellow X. What use does the handbook allow for that lane?
Correct answer: Preparing to turn left.
The handbook distinguishes a flashing yellow X, allowing preparation for a left turn, from a steady yellow X, which directs traffic to leave the lane.

Your car has air bags. Why should everyone still wear the proper belt or child restraint?
Correct answer: Air bags supplement restraints and do not replace belt protection, including in later impacts.
Air bags provide supplemental protection and deflate after deploying. Proper restraints remain essential and help keep occupants in position.

You reach the sign shown at a quiet intersection. What does it require even when no traffic is visible?
Correct answer: A complete stop before proceeding when safe.
STOP requires a full stop, not merely a reduction in speed. Use the stop line, or the appropriate crosswalk or intersection stopping position, then yield before proceeding.

What instruction does this triangular sign give as you approach crossing traffic?
Correct answer: Slow down and give way, stopping if necessary.
YIELD means give the right-of-way to traffic in the intersection or road you are entering. Slow enough to assess the situation and stop when needed.

This sign faces you at a roadway opening. Which action follows its instruction?
Correct answer: Do not use that opening to enter the roadway.
DO NOT ENTER prohibits entry from the direction you are approaching. An empty roadway does not cancel the restriction; find a lawful entrance.

You see this sign facing your vehicle after a turn. What danger does it identify?
Correct answer: You are traveling toward opposing traffic in the wrong direction.
WRONG WAY warns that you have entered against the permitted traffic direction. Correct the mistake as quickly and safely as possible; do not continue farther into oncoming traffic.

Which maneuver is ruled out by this symbol?
Correct answer: Turning left.
The red slash cancels the left-turn movement shown by the arrow. It does not itself prohibit going straight or establish priority over pedestrians.
