[b]Rules on warning triangle and high-vis jackets enforced, France[/b]
[quote]THE period of 'education' on new rules covering the need to carry a warning triangle and high visibility jacket in your car comes to an end on October 1.

From that date the gendarmerie will begin to enforce the regulations, failure to have a triangle or jacket in your car will mean a fine of €90 for each offence, and the equipment has to meet EU standards.

Also on the same date rules requiring cyclists to wear high-visibility jackets will be enforced, requiring jackets to be worn when outside towns, at night or when visibility is poor during the day.[/quote]
