We can’t argue with your reasoning, its warmer, there are less cars, the roads are better, the wine is better……………..
But if the car is a company car, then you will need a VE103B with you at all times. It is essentially proof that permission is given for you to take the vehicle abroad. You get one by contacting your leasing company or if you are a Carlease UK customer contact us. You can download one here if you need one quickly.
Additionally, you need to check with your company that your car is insured abroad and whether you need a separate green card, with accident description paperwork. Always make sure you have both parts of your licence with you and scan it and email to yourself as a back up.
To go anywhere in Europe you will pass through or be going to France. Its now a legal requirement that you have at least one breathalyzer kit. You must also have two hi-vis vests along with at least one warning triangle, all for use in the event of an incident.
In Germany this law is applied even more strictly where the zero tolerance was the first in Europe. In Germany, just because you are on an autobahn, do not assume that there is no limit. 35% of the autobahn kilometres are limited to either 80 km/h or 130 km/h. This is again strictly enforced. On the autobahn, ensure you have plenty of fuel, it is illegal to run out and the fines are prohibitive. Daylight driving lights are required or dipped beam in both countries. Both countries also require spare bulb packs.
