South Carolina's Car Seat and Booster Seat Requirements for Children

What South Carolina requires for child car seats

South Carolina law requires children under age 8 or shorter than 4 feet 9 inches to ride in a car seat or booster seat, depending on their age and size. The specific type of seat depends on the child's age and weight. Children under age 2 must use a rear-facing car seat. Children ages 2 through 7 must use a forward-facing car seat with a harness or a booster seat. Children ages 8 and older, or those who reach 4 feet 9 inches tall, may use a regular seat belt.

The law applies to all passengers in a vehicle, whether they are traveling within South Carolina or passing through. Violations result in a fine, though the fine amount varies depending on the specific violation and whether it is a first or repeat offense. The law also allows for a safety seat exception: if a vehicle does not have a working seat belt or the child has a medical condition that makes a car seat unsafe, you may request a waiver from the South Carolina Department of Motor Vehicles.

Key Takeaways

  • Children under age 2 must ride in a rear-facing car seat; children ages 2 through 7 must use a forward-facing car seat with a harness or a booster seat.
  • The law applies to all children under age 8 or shorter than 4 feet 9 inches, regardless of where you are driving in South Carolina.
  • A child may transition out of a booster seat once they reach age 8 or 4 feet 9 inches in height and can use a regular seat belt instead.
  • Violations of the car seat law result in a fine; repeat violations carry higher penalties.
  • You can request a safety seat exception from the Department of Motor Vehicles if your vehicle lacks a working seat belt or your child has a medical condition.

Rear-facing car seats for infants and toddlers

Rear-facing car seats are required for all children under age 2, regardless of size. A rear-facing seat protects the child's head, neck, and spine in a crash by distributing the force of impact across the entire back of the seat. The child sits facing the back of the vehicle.

Rear-facing seats come in two types: infant-only seats, which are designed for newborns through about 35 pounds, and convertible seats, which can be used rear-facing from birth and then switched to forward-facing as the child grows. Both types are legal under South Carolina law. You must install the seat according to the manufacturer's instructions and secure it with either the vehicle's seat belt or the LATCH system (Lower Anchors and Tethers for Children), which is built into most vehicles made after 2002.

Forward-facing car seats and booster seats for older children

Once a child reaches age 2, you may switch to a forward-facing car seat with a harness. The child faces forward and is held in place by a five-point harness (straps over both shoulders, both hips, and between the legs). Forward-facing seats are typically used until the child reaches the weight or height limit set by the manufacturer, which is often around 40 to 65 pounds depending on the seat.

After a child outgrows the forward-facing seat, a booster seat is required until age 8 or until the child reaches 4 feet 9 inches tall. A booster seat lifts the child so that the vehicle's seat belt fits properly across the child's chest and lap. The seat belt, not the booster seat itself, holds the child in place. Booster seats come in two types: high-back boosters, which provide head and neck support, and backless boosters, which are smaller and more portable. Both are legal in South Carolina.

Seat belt use for children age 8 and older

Once a child reaches age 8 or grows to 4 feet 9 inches tall, they may use the vehicle's regular seat belt instead of a booster seat. The seat belt should fit snugly across the child's chest and lap. If the seat belt does not fit properly—for example, if it crosses the child's neck or sits too high on the lap—continue using a booster seat until the child is large enough for the belt to fit correctly.

Children age 8 and older are still required to wear a seat belt at all times while the vehicle is moving, just as adult passengers are. Failure to wear a seat belt results in a separate fine under South Carolina law.

Installation and car seat safety standards

Car seats sold in the United States, including those sold in South Carolina, must meet federal safety standards set by the National Highway Traffic Safety Administration (NHTSA). All new car seats come with an instruction manual that explains how to install the seat correctly in your vehicle. Installation errors are common and can reduce the seat's effectiveness in a crash.

Many hospitals, fire departments, and police departments in South Carolina offer free car seat installation checks. A trained technician will inspect your seat to make sure it is installed correctly and that the harness or seat belt is adjusted properly for your child. You can search for a local installation site through the NHTSA website or by calling your local fire department or hospital.

Exceptions and medical waivers

South Carolina law allows for exceptions in specific situations. If your vehicle does not have a working seat belt or LATCH system, or if your child has a medical condition that makes riding in a car seat unsafe or impractical, you may request a waiver from the South Carolina Department of Motor Vehicles. A medical waiver requires documentation from a licensed physician explaining why the car seat is unsafe for your child and what alternative safety measures you will use instead.

To request a waiver, contact the South Carolina Department of Motor Vehicles directly. You will need to provide the physician's documentation and information about your vehicle. The DMV will review your request and notify you whether the waiver is approved. A waiver is not automatic and applies only to the specific child and vehicle named in the request.

Penalties for violations

Violating South Carolina's car seat law results in a fine. The amount of the fine depends on whether it is your first violation or a repeat offense. A first violation typically results in a fine of between $100 and $200. Repeat violations carry higher fines. The fine is separate from any other traffic citations you may receive.

Law enforcement officers may stop a vehicle if they observe a child not properly restrained. The officer will issue a citation, which you can pay or contest in traffic court. Some jurisdictions offer the option to dismiss the citation if you show proof that you have since obtained a proper car seat and had it installed correctly.

Frequently Asked Questions

Can my child sit in the front seat?

South Carolina law does not explicitly prohibit children from sitting in the front seat, but federal safety guidelines recommend that all children under age 13 ride in the back seat. The back seat is safer in a crash because it is farther from the dashboard and airbags. If your child must sit in the front seat, they still need the appropriate car seat or booster seat for their age and size.

What if I am traveling out of state with my child?

You must follow the car seat laws of the state you are in. Most states have similar requirements to South Carolina, but some have different age or height thresholds. Before traveling, check the car seat laws of the states you will be driving through or visiting to make sure your child's seat meets those requirements.

Do I need to use a car seat in a taxi or rideshare vehicle?

South Carolina law exempts taxis and for-hire vehicles from the car seat requirement, though using a car seat is still safer. If you regularly use rideshare services with your child, you may want to invest in a portable car seat that you can install in different vehicles, or ask the rideshare company whether they provide car seats.

What should I do if my car seat was in a crash?

Most manufacturers recommend replacing a car seat after any crash, even a minor one, because the impact may have damaged the seat's structure in ways you cannot see. Check your car seat's instruction manual for the manufacturer's specific guidance. Some insurance companies cover the cost of replacing a car seat after a crash.

Where can I buy a car seat in South Carolina?

Car seats are sold at most retailers that carry baby products, including big-box stores, baby specialty stores, and online retailers. Prices vary widely depending on the type and brand of seat. Some community organizations and nonprofits in South Carolina offer discounted or free car seats to families who cannot afford them; contact your local health department or hospital for information about programs in your area.
