Rule 98 : The Essential Guide to Safe Towing
Phase 1 : Before You Set Off
Verify Your License Permissions
Drivers who passed car test on / after 1 Jan 1997 face specific weight restrictions on trailers they are permitted to tow .
The Roadworthy Checklist
Confirm all trailer tyres are legal , braking system fully functional , and all lights working correctly .
Fit a Secondary Coupling: Your trailer must be equipped with a safety chain or similar device to prevent detachment .
Weight Distribution & Tow Ball Load
Minimize risk of ' snaking ' or loss of control .
Visibility and Lighting Adjustments
Use towing mirrors if load obstructs rear view , and adjust headlights for trailer's weight .
Phase 2 : On the Road
Motorway Lane Restrictions
How to Correct ' Snaking '
Increased Stopping Distances. Account for significantly longer stopping distances when towing a heavy load .
Motorway Lane Restrictions: Prohibited from driving in the right - hand lane of a motorway with three or more lanes .
If trailer swerves , ease off accelerator and reduce speed gently .
Never brake harshly ; can cause total loss of control .
Reduced Speed Limits Be aware that lower speed limits apply specifically to vehicles towing trailers .
Phase 3 : In the Event of a Breakdown
Use Professional Recovery
Towing with a simple rope is dangerous : a solid tow bar or professional recovery service is highly recommended .
Rejoining the Carriageway
Be prepared for it to take much longer than usual to build up speed when re - entering traffic from the shoulder .
