Vehicle Inspections: new battery cooling checks for electric and hybrid vehicles

The Government has introduced changes to vehicle inspection procedures to improve safety and respond to the fast-growing use of electric and hybrid vehicles in Monaco. Inspections now include a check on the coolant level in the batteries that power electric and hybrid vehicles.

The new measure came into effect on 21 March 2026, and allows inspectors to detect a drop in coolant level, even when no visible leak is present. It complements existing checks, which previously focused mainly on detecting leaks, and aims to prevent battery damage and the risk of thermal runaway. In addition to improving safety, the check helps maintain battery performance and lifespan, protecting the vehicle’s value.

The coolant level is checked visually. If it is found to be low, it must be topped up by a qualified automotive professional, as the coolant tank is sealed for safety reasons. Any follow-up inspection required is free of charge.

This measure adds to the existing checks and forms part of an ongoing effort to adapt Monaco’s regulations to changes in the country’s vehicle fleet. Other technical changes are also being introduced, including checks of the eCall emergency system, inspection of certain structural vehicle components, and verification of required documents for specific types of specialised transport.

These changes will not affect the cost of the vehicle inspection.
