The ANTAI fine can best be compared to the Dutch CJIB fine, in that the ANTAI acts as a central collection agency for French fines. This makes transferring fines to the renter considerably less complicated, now that you have to deal with fewer different parties (such as all kinds of individual municipalities with their own processes).
ANTAI fines are bascially the most common offenses such as speeding.
The deadline for making objections is 48 days, which can be done by post or digitally via the ANTAI website. The ANTAI also offers a digital connection with which fines and transfer requests can be exchanged automatically.
