Recommendation R482 of the French Health Insurance covers mobile construction machinery: excavators, loaders, dump trucks, compactors, bulldozers, graders and telehandlers. The version in force is R.482B, published in September 2026, which keeps the assessment method in place since 1 January 2020. It is the only one of this site’s five recommendations whose CACES is valid for 10 years, against 5 for the others. The theory test, shared by all categories, has a five-theme marking scheme, including a traffic theme worth 12 points and an end-of-shift and maintenance theme worth only 4 points: two mistakes are tolerated there, not three. Courses cost more than for forklifts: as of 23 October 2026, the median price of an initial category A course is €1,560 in the Mon Compte Formation catalogue, and €1,450 for category B1.

Machines outside the CACES
Some construction machines fall under no category, such as pavers, cold planers or walking excavators. Their operator follows training specific to the machine, assessed by the employer before the operating authorisation. The tool on the which CACES for which machine page flags them.
