The outcome of the inter-ministerial committee on road safety can be found here:
http://bit.ly/kC8gZyIt's a wish list of measures, some of which can be implemented straight away, some will require legislation. But they will happen - the committee says of 103 measures decided since 2008, 101 have been put into effect.
This is the point to beware of when heading to LM this year:
"Without waiting for these measures to be put into effect, the prime minister called on the interior minister...to put in place extra checks on the roads, especially during the long weekends in June".France already has pretty hefty fines for speeding etc (1500E for 50kph+ over the limit)- this suggests they will be enforced rigorously.
Incidentally, the new speeding penalties would make the same offence punishable by 3 months in prison. Given that more than 25 000 people were caught doing just that last year, french jails could get very full indeed.
