This additional premium may not exceed 100% of the reference premium. This ceiling is reduced to 50% for novice drivers who have obtained their driving licence under the conditions referred to in article R. 123-3 of the Highway Code.
It is reduced by half its initial rate after each year, consecutive or otherwise, without a claim incurring liability.
In the event of a change of insurer, the new insurer may apply the same additional premium to the insured as the previous insurer could have applied under the previous paragraphs.
Proof of the years of insurance is provided, in particular, by the statement of information provided for in article 12 of the appendix to article A. 121-1 or any other equivalent document, for example, if the insurance is taken out outside France.
