When it comes to towing a trailer in Ireland, the requirements aren’t as straightforward as you might think. Whether you need a specific licence depends on a few key factors, such as the weight and type of trailer you’re towing. In this guide, I’ll help you understand what’s required and how to make sure you’re towing legally.

Do You Need a Category EB Licence?
If you’re towing a trailer, there’s a good chance you’ll need a Category EB licence, especially if:
- The trailer has a double axle.
- You’re transporting animals in a horsebox or cattle trailer.
- The total weight of your trailer exceeds 750 kg.
- The combined weight of your car, trailer, and its load is more than 3,500 kg.
Without a Category EB licence, you aren’t legally covered for towing these types of loads. Relying on a standard Category B licence in these cases could result in serious consequences if you’re stopped by the Gardaí or involved in an accident, including a potential 12-month driving ban and an insurance denial.

What Happens if You Tow Without the Right Licence?
If you’re towing without a proper Category EB licence and you’re caught or involved in an accident, the consequences can be severe. Not only could your vehicle be impounded, but you could also face a court appearance, a possible driving ban, and insurance issues. In the event of an accident, your insurance provider may refuse to cover damages if you’re towing illegally, potentially leaving you with costly out-of-pocket expenses.

Who Typically Needs a Trailer Licence?
Various professions and activities require towing heavier loads. For example:
- Farmers, animal owners, and equestrian centres often need to tow livestock.
- Builders, landscapers, and ground workers frequently tow tools and heavy machinery.
- Sports enthusiasts may tow equipment such as boats, caravans, or rally cars.
Exceptions for Small Trailers
With a Category B licence, you can tow light, single-axle trailers, typically with a maximum weight capacity of 750 kg. However, this limit varies based on your vehicle’s make and model, so it’s crucial to check your specific vehicle’s towing capacity to ensure compliance.
Employers and Towing Licences
If your business requires employees to tow trailers, you can expense the cost of trailer lessons and tests as a training expense. I include eco-driving training in my jeep and trailer lessons to help keep fuel and maintenance costs down, making this an economical choice for your company’s needs.
How to Obtain Your Trailer Licence (Category EB)
To legally tow larger trailers, you’ll need to:
- Complete a theory test.
- Obtain a provisional licence or learner permit for towing.
- Book and pass the practical driving test for Category EB.
