Drivers hiring a car abroad will now have three weeks to share extra driving licence details with rental companies instead of three days.
Motorists are required under a new system to access the DVLA website to generate a check code that allows companies to see whether a driver has penalty points.
The code was introduced after the paper counterpart licence that carries such details was computerised.
The DVLA initially allowed the code to stay "live" for just 72 hours. The checking period is now 21 days.
