Going on holiday with a caravan? Know the rules before you set off

Travelling with a caravan or trailer is, for many, a symbol of freedom. Being able to take your home with you, plan stops as you go and explore less touristy landscapes has become increasingly popular in Portugal. But before you hit the road, it’s essential to know the legal requirements to ensure a safe and lawful journey.

What driving licence do you need?

Not all trailers or caravans can be driven with a regular Category B licence. The type of licence required depends on the Maximum Authorised Mass (MAM) of the vehicle + trailer combination:

• Category B: allows driving trailers up to 750 kg MAM, or combinations (vehicle + trailer) with a total up to 3,500 kg;

• Extension B96: required if the total exceeds 3,500 kg but does not exceed 4,250 kg;

• Category BE: mandatory when the total exceeds 4,250 kg or if the trailer exceeds 750 kg and the combination surpasses the limits of the previous categories.

Before travelling, check the weight of the vehicle and the trailer/caravan on both registration documents.

Maximum speed limits with caravan or trailer

Whether on a motorway or a national road, driving with a trailer involves specific speed limits:

• Motorways: maximum 100 km/h (even if the general limit is 120 km/h);

• Main and complementary roads (IP/IC): 90 km/h;

• Other roads outside built-up areas: 80 km/h;

• Within built-up areas: 50 km/h (general rule, unless otherwise signposted).

These limits apply to most vehicle combinations, but you should always check for specific limitations in the vehicle registration.

Signalling and safety rules

When travelling with a caravan or trailer, there are additional legal requirements:

• Additional exterior mirrors if the originals don’t provide good rear and side visibility;

• Functional lights and reflectors on the trailer or caravan, electrically connected to the towing vehicle;

• Warning triangle and reflective vests are mandatory for both the vehicle and trailer;

• Trailers with MAM over 750 kg must have their own civil liability insurance policy.

Driving, parking and overnight stays

In Portugal, sleeping in a caravan is not illegal, but there are important restrictions:

• Outside campsites, camping or overnight stays are not allowed in protected areas or sensitive natural zones, such as the Southwest Alentejo and Vicentine Coast Natural Park;

• Parking must comply with general vehicle rules and must not compromise road safety or public access;

• Some local authorities enforce specific caravan regulations, so it’s advisable to check before overnighting in public areas.

Useful tips for a safe roadtrip

• Check tyre pressure for both vehicle and trailer/caravan;

• Distribute the load evenly to avoid overloading the rear axle;

• Ensure proper hitching and secure locking of the trailer;

• Test rear lights and indicators before departure;

• Consider installing a stabilisation system for added comfort while driving.
