Towing mirrors: extension mirrors for caravans and trailers
If your caravan or trailer blocks the view behind you, towing mirrors give you the visibility you need.
What are towing mirrors?
Towing mirrors, also called extension mirrors, let you see past a caravan, trailer or horsebox that is wider than your car. Standard wing mirrors often cannot see around the sides of a wide load, so an extra mirror, or an extended one, makes towing safer.
Types of towing mirror
| Type | How it works | Good for |
|---|---|---|
| Clip-on or strap-on | Fits over your existing wing mirror with straps or clamps | Occasional towing. Easy to remove afterwards. |
| Vehicle-specific | Made to fit your car or van model | A neat fit and stable view |
| Extendable arm | Replacement mirror with an arm that extends out | Regular towing with wide loads |
| Add-on convex mirror | A small mirror stuck onto the glass to widen the view | Extra blind spot help. Not a full towing solution. |
How to choose
- Check how wide your trailer or caravan is compared with your car's mirrors.
- Decide how often you tow. Clip-ons suit occasional use, and vehicle-specific or extendable mirrors suit regular towing.
- Match your car. Mirror size and shape differ, so check the mirror fits your model.
- Check stability. A mirror that shakes at speed is not much use.
Check the rules
Requirements for mirrors when towing can apply. Check the current guidance from the Road Safety Authority and your vehicle and trailer documents, as rules and your own setup matter. This is general information only.
Tips before you tow
- Fit the mirrors and adjust them before you set off, sitting in the driver's seat.
- Test the view at the kerb or in an empty car park.
- Remove clip-on mirrors when you are not towing.
- If your normal mirror is damaged, fix it first. See wing mirror replacement.

They are designed for temporary use. If you tow regularly, vehicle-specific or extendable mirrors may suit you better.
