Key Factors for Choosing the Best Trailer
In addition to the type of trailer, there are several essential features you should consider.
2.1. Load capacity and GVW
The Maximum Authorized Mass (MAM) is the total weight that the trailer can support including the load.
Light: ≤ 750 kg (You do not need your own insurance or MOT.)
Heavy: > 750 kg (You need your own insurance and MOT.)
Advice: Consult your car's owner's manual to verify the maximum towing capacity allowed.
Hitch type and vehicle compatibility
The trailer hitch must be compatible with the vehicle. There are several types:
- Fixed ball: Economical, but cannot be disassembled.
- Detachable ball: Allows you to remove the hitch when not in use, avoiding fines.
- Retractable hitch: Hidden when not in use, ideal for modern cars.
Always check the hitch compatibility with your vehicle before installation.
Braking system
If the trailer weighs more than 750 kg, it must have a braking system.
- Trailers without brakes: Only suitable for light loads.
- Trailers with inertia brakes: Improves road safety.
If you carry heavy loads, opt for a braked trailer to avoid accidents.
Construction material
The material of the trailer influences its durability and weight:
- Galvanized steel: Stronger, but heavier.
- Aluminum: Lightweight and corrosion resistant, ideal for long journeys.
- Plywood: Economical, but less durable.
If the trailer will be exposed to the elements, it is advisable to choose one with anti-corrosion treatment.
Safety and stability on the road
To ensure safe trailer driving, keep these points in mind:
- Quality tires and with the appropriate pressure.
- Balanced load distribution to avoid swaying.
- Additional stabilizers for greater safety on long journeys.
Advice: If you are transporting fragile cargo, use tie-down straps to prevent sudden movements.
Regulations and approval
Depending on the weight of the trailer, different regulations may apply:
- Trailers over 750 kg require registration and own insurance.
- Some models require Periodic ITV to ensure its status.
- Rear lights and turn signals are mandatory on all trailers.
If you plan to travel abroad, check the regulations of your destination country.
