Belmopan and other large towns are very busy and parking can be scarce towards the main commercial areas. Elsewhere, you’ll find ad hoc parking by the side of most main roads and it’s always free. Try to park where your car is visible, especially at night. Whilst crime is lower than in some Central American countries, it's still prevalent.
If you want the security of attended parking you’ll need to pay for it. You’ll generally find it only in the bigger towns and cities where there’s also roadside metered parking in the commercial areas.
Enforcement of parking is rarely enacted unless you have parked inconsiderately or for an extended period of time. Most parking regulation is relaxed in Belize.
Belize doesn’t officially recognise the needs of disabled drivers but it’s possible to get assistance and a more convenient space in attended garages.
