Aggregate Trailer Mass (ATM)

It sounds like you are working with a trailer that has a maximum Aggregate Trailer Mass (ATM) of 750kg, which doesn’t require brakes according to regulations. Here’s some more detailed information and considerations for towing with this setup:

Key Points:

1. Aggregate Trailer Mass (ATM): This is the total mass of the trailer when it is fully loaded. For your trailer, the ATM is 750kg.
2. Un-braked Towing Capacity: This refers to the maximum weight that your tow vehicle can safely tow without trailer brakes. It is essential to check this specification for your vehicle, as it can vary. Some smaller vehicles might have an un-braked towing capacity less than 750kg, in which case they wouldn’t be suitable for towing your trailer without brakes.

Steps to Ensure Safe Towing:

1. Check the Tow Vehicle’s Specifications:
   • Refer to the owner’s manual of your vehicle.
   • Look for the section on towing, which will specify the un-braked towing capacity.
   • Ensure that this capacity is at least 750kg.
2. Understand Trailer Weight Distribution:
   • Ensure the load is balanced and secure.
   • Check that the mass on the towing vehicle (C) and the mass on the tyres are within safe limits to maintain stability during towing.
3. Regular Inspections:
   • Even though brakes are not required, regularly inspect your trailer’s tyres, lights, and coupling to ensure everything is in good working order.
4. Drive Carefully:
   • Adjust your driving style to accommodate the extra load.
   • Maintain a safe distance from other vehicles and allow for extra braking distance.
