Transporting vehicles across short or long distances can be challenging, especially if you need to ensure the safety and security of the car during transit. This is where car trailers come in. This blog will explore everything you need to know about car trailers, their purpose, and their specific regulations in South Africa. We’ll also address common questions to help you make an informed decision when considering a car trailer for your needs. Let’s get started!
What is the Meaning of a Car Trailer?

A car trailer is a specialised type of trailer designed for transporting cars. Unlike general-purpose trailers, car trailers are constructed specifically to accommodate vehicles’ size, shape, and weight, ensuring they are securely carried from one location to another. They typically feature ramps for easy loading and unloading and secure tie-down points to keep the vehicle in place during transit.
Car trailers can vary in design, but the main objective is to provide a safe and efficient way to transport cars. Some car trailers are open, exposing the car to the elements, while others are enclosed to provide additional protection from weather conditions, debris, and other hazards on the road. Car trailers can be used for multiple purposes, from moving personal vehicles to towing race cars, classic cars, or vehicles for sale.
Why is it Called a Trailer?
The term “trailer” originates from the word “trail,” which means to follow or be dragged behind. A trailer is an unpowered vehicle towed by another vehicle, such as a car, truck, or van. It’s called a trailer because it trails behind the towing vehicle, relying on it for movement. Trailers, including car trailers, are equipped with wheels and axles but lack engines, so they must be pulled.
A car trailer is specifically designed to trail behind the towing vehicle while carrying another vehicle on its platform. Its design focuses on easy towing, stability, and safety to ensure that the car being transported reaches its destination without any issues.
What is the Main Purpose of a Car Trailer?
The primary purpose of a car trailer is to transport cars safely and efficiently over long or short distances. Car trailers are commonly used in various scenarios, including:
Relocation of Personal Vehicles
Moving to a new city or province in South Africa? Instead of driving multiple cars across long distances, a car trailer allows you to tow one vehicle while driving another, saving fuel, wear and tear, and effort. It’s a convenient way to transport your car without adding unnecessary mileage to the odometer.
Transporting Race Cars or Classic Cars
Transporting high-value or delicate vehicles can be nerve-wracking for car enthusiasts, collectors, and racers. Car trailers, especially enclosed ones, provide a safe and secure way to transport these prized possessions to events, shows, or races, ensuring they remain pristine throughout the journey.
Delivery of Cars for Sale
Car dealerships and sellers often use car trailers to deliver vehicles to buyers, especially when dealing with inter-city or long-distance transactions. It ensures that the car arrives in the same condition it was sold in, giving buyers peace of mind and protecting the seller’s reputation.
Vehicle Recovery
Car trailers are also used to recover broken-down or damaged vehicles. Tow trucks equipped with car trailers can retrieve vehicles from accident scenes or locations where they’ve stopped working, transporting them to repair shops or scrapyards.
Types of Car Trailers for Different Needs
Choosing the right type of car trailer can be a game-changer. Here are the main types available:
Open Car Trailers
- Description: Open trailers are flat, open platforms with no enclosure, making them lightweight and cost-effective.
- Best For Those looking to transport vehicles short distances or in good weather conditions.
Enclosed Car Trailers
- Description: These trailers have enclosed bodies that protect the vehicle from weather and road debris.
- Best For Car enthusiasts, race car owners, or anyone transporting a high-value vehicle.
Tilt Car Trailers

- Best For Low-clearance vehicles or frequent loading/unloading.
Flatbed Trailers with Car Carriers
- Description: These are large trailers with designated car carriers, allowing multiple vehicles to be transported.
- Best For Car dealerships, transport companies, or businesses needing to move several vehicles at once.
How Many KGs is a Car Trailer?
The weight of a car trailer can vary depending on its design, size, and purpose. In South Africa, car trailers are classified based on their Gross Vehicle Mass (GVM), which includes the weight of the trailer itself plus the maximum load it can carry. Here are some general categories:
- Lightweight Car Trailers typically weigh between 500 kg and 1,500 kg. They are designed for smaller cars or lighter loads and are often easier to tow.
- Standard Car Trailers: These can weigh between 1,500 kg and 3,500 kg and are suitable for various vehicle sizes. They are robust enough to carry most standard-sized vehicles.
- Heavy-Duty Car Trailers: These trailers can weigh 3,500 kg and are designed for heavier or larger vehicles. They are often used for trucks, SUVs, and larger sedans.
It’s essential to know the weight of the car trailer you’re considering because it affects the towing capacity of the vehicle pulling it. Overloading a trailer can lead to dangerous situations, including loss of control, accidents, and mechanical issues.
Safety Tips for Towing a Car Trailer

Safety should always be a priority when using a car trailer. Here are some tips for safe towing:
1. Check Weight Limits: Always verify the trailer’s weight limit and ensure you are within the safe range for both the trailer and the towing vehicle.
2. Inspect Trailer Condition: Regularly inspect the trailer for wear and tear, including brakes, lights, and tyres.
3. Balance the Load: Distribute weight evenly across the trailer, keeping heavier items closer to the front to prevent swaying.
4. Use Safety Chains: Always attach safety chains between the trailer and the towing vehicle.
5. Drive at Safe Speeds: Reduce speed and maintain a greater following distance to allow for longer stopping distances when towing a trailer.
Maintenance Tips to Keep Your Car Trailer in Top Condition
Maintaining your car trailer is essential for its longevity and performance. Regular maintenance can prevent breakdowns and keep the trailer safe. Here’s a maintenance checklist for car trailers:
1. Inspect Tires and Pressure
- Ensure the tyres are in good condition, with no visible wear, cracks, or punctures. Check the tyre pressure regularly, as under-inflated tyres can lead to instability.
2. Brake System
- Test the trailer’s brakes periodically, especially before long trips. Brakes are essential for trailers over 750 kg, so it’s important to ensure they’re in working order.
3. Check Lights and Electricals
- Trailer lights must be in good working condition. Test brake lights, indicators, and hazard lights to ensure visibility and communication on the road.
4. Lubricate Moving Parts
- Hinges, joints, and other moving parts should be lubricated to prevent rust and ensure smooth operation.
5. Rust Prevention and Repairs
- For trailers exposed to harsh weather or frequent use, inspect for rust and apply protective coatings to prevent corrosion.
What are the Trailer Laws in South Africa?
South Africa has strict regulations governing trailers, including car trailers. Understanding these laws is crucial to avoid penalties, ensure road safety, and comply with legal requirements. Here are some key regulations to keep in mind:
Licensing and Registration
Car trailers must be licensed and registered with the appropriate authorities. Each trailer must have a unique license plate and be roadworthy to ensure it meets the safety standards set by the government. When purchasing or building a trailer, ensure it’s registered to avoid legal complications.
Towing Capacity
The vehicle used to tow the car trailer must have a towing capacity that matches or exceeds the weight of the trailer and its load. Exceeding your vehicle’s towing capacity can lead to dangerous driving conditions, engine brakes, and suspension damage. Always check the manufacturer’s specifications for towing capacity and ensure it’s compliant with your needs.
Brake Requirements
South African law mandates that trailers with a GVM of more than 750 kg must be equipped with brakes. Trailers with a GVM exceeding 3,500 kg must have a dual braking system that operates independently of the towing vehicle’s brakes. This ensures that the trailer can stop safely, even in emergencies.
Lighting and Reflectors
Car trailers must have proper lighting and reflectors to ensure they are visible to other drivers on the road, especially at night or in low-visibility conditions. This includes brake lights, indicator lights, and reflectors on the sides and rear of the trailer.
Roadworthiness and Safety Checks
Regular maintenance and safety checks are essential to keeping your car trailer roadworthy. This includes checking the tires, brakes, lights, and hitch to ensure everything works properly. South African law requires trailers to undergo roadworthy tests at specific intervals to ensure their safety.
