Many French motorways have off peak rates.Finding which one not so easy. "there are tariff modulations on the SANEF A1 and A14 motorways (North and East of France). On the A1 on Sundays, bank holiday Mondays and certain bank holidays, prices drop by 25% in green fare between 2:30 p.m. and 4:30 p.m. and between 8:30 p.m. and 11:30 p.m. h 30 and 20 h 30 (time of passage at the barrier). On the A14, a reduced rate applies on weekdays outside peak hours, i.e. between 10 a.m. and 4 p.m. and from 9 p.m. to 6 a.m."
