A 20-month-old child is still within the rear-facing seat's height and weight limits. In a family car with a rear seat, which restraint is required?
Correct answer: A correctly fitted rear-facing child seat in the rear.
A child under two who has not exceeded the rear-facing seat's limits must remain properly secured rear-facing in a rear passenger seat.

A three-year-old has outgrown the rear-facing seat but still fits a suitable forward-facing child seat. Which restraint should be used in the rear seat?
Correct answer: The forward-facing child seat with its harness.
The forward-facing stage uses a harness until the child exceeds that restraint's maximum height or weight requirements. A booster is not a replacement merely because the child is three.

A five-year-old has outgrown the forward-facing harness and is not ready for a properly fitting adult belt. What is the next required restraint?
Correct answer: A belt-positioning booster in a rear seat.
A child at least four who has outgrown the forward-facing restraint uses a belt-positioning booster until the adult-belt requirements are met.

Which belt arrangement must be used with a belt-positioning booster?
Correct answer: Both a lap belt and a shoulder belt.
The booster rule requires both lap and shoulder belts. A lap-only seating position is not suitable for this type of booster.

A seven-year-old is 57 inches tall and meets every listed adult-belt fit condition. Does the South Carolina rule permit use of the adult belt?
Correct answer: Yes; the height alternative applies when the belt fits properly.
The rule uses age eight or height 57 inches, together with proper belt fit. Reaching the height threshold does not remove the fit requirement.

A child has turned eight, but the adult belt crosses the abdomen and neck. Does the birthday alone establish proper belt fit?
Correct answer: No; the belt must also meet the listed fit conditions.
Age alone does not establish that an adult belt secures a child properly. The statute lists lap-belt, shoulder-belt and seated-posture conditions.

Which combination shows the adult belt fits a child properly?
Correct answer: Lap belt on hips and thighs, shoulder belt across the chest, and knees bending at the seat edge without slouching.
Proper fit includes all three checks: belt placement at the hips/thighs and center of the chest, plus sitting against the seat back with knees bending over the edge.

Your 16-year-old passenger has no driver's license or beginner's permit and is not wearing the available belt. Who has the duty to require its use?
Correct answer: You, as the driver.
Drivers are responsible for requiring occupants 17 or younger to use the appropriate restraint, except for the statute's credentialed-minor exception.

A 17-year-old passenger with a valid driver's license refuses to wear a belt. Under the statute's responsibility exception, who violates the belt requirement?
Correct answer: The licensed passenger.
The licensed minor remains required to buckle up but is personally responsible for this violation. The exception changes responsibility, not the duty to wear the belt.

A person claims a physical or medical reason prevents belt use. What does the statutory exception require?
Correct answer: Written verification from a physician.
The medical exception requires written physician verification. Personal preference or discomfort alone is not the documented exception.

A child's documented medical needs prevent use of a standard child restraint. What does the law provide?

At midday, steady rain requires continuous windshield-wiper use. What must you do about your vehicle's lights?
Correct answer: Switch on the required driving lights, not just parking lights.
Wiper use because of rain triggers the lighting requirement, apart from the narrow intermittent-mist exception. Parking lights alone do not satisfy it.

In daytime mist, your wipers run intermittently and people and vehicles remain clearly visible more than 500 feet ahead. Does wiper use alone trigger this statute's lighting requirement?
Correct answer: No; the intermittent-mist exception applies, although lights can improve visibility.
The statute excepts intermittent wiper use in misting rain, sleet or snow. Separate darkness and severely reduced-visibility requirements still apply when their conditions exist.

Dust severely reduces daylight visibility so you cannot clearly distinguish people and vehicles 500 feet ahead. What is required?
Correct answer: Turn on the required vehicle lights.
Lighting is required when weather or environmental conditions severely reduce the specified 500-foot visibility, even during daylight and without wiper use.

On an otherwise clear day, which time period is expressly included in South Carolina's lighting requirement?
Correct answer: Half an hour after sunset through half an hour before sunrise.
The statute specifies this nighttime interval. Other conditions can require lights earlier or later, so this is not a reason to drive unlit when visibility is poor.

At what distance from an oncoming vehicle must you avoid projecting headlight glare into its driver's eyes?

At night you follow another car without overtaking it. At what following distance does the law require a beam other than the high beam?
Correct answer: Within 200 feet of the car ahead.
Within 200 feet behind another vehicle, use a permitted lower beam. The statute separately identifies an overtaking-and-passing exception.

What is the basic front-headlamp requirement for an ordinary car used at night?

One of your car's fitted brake lights has failed. Is daylight a reason to leave it unrepaired?

Stop and signal lamps must remain in good working condition. They communicate braking and turning in daylight as well as at night.
