What’s the speed limit for a car towing a trailer on a motorway?

Explanation: If you're towing a small, light trailer, it won't reduce your vehicle's performance by very much and it may not be visible in your mirrors. However, strong winds or buffeting from large vehicles might cause the trailer to snake from side to side. Be aware of your speed and don't exceed the reduced speed limit imposed on vehicles towing trailers.
