Billund Airport Car Rentals: Best Rates & Zero Hidden Fees

US citizens can drive in Denmark with their valid US driver's license for up to 90 days. However, an International Driving Permit (IDP) is strongly recommended and often required by rental companies—it translates your license into 10 languages including Danish. Get one from AAA ($20) before departure. Without it, you risk being turned away or facing issues during police checks.

Most rental companies in Denmark charge an additional fee of 100-150 DKK ($15-22) per day for drivers under 25, sometimes called a 'young driver' or 'under-25 surcharge.' Some companies set the minimum age at 20 for certain vehicle classes. Always confirm the exact fee when booking, as it can significantly increase your total cost—budget an extra $100-150 for a week-long rental.

Yes, the famous Øresund Bridge connecting Denmark to Sweden costs 415 DKK ($60) for a single crossing (discounted to 280 DKK/$40 with AutoPASS). Denmark also has several other toll routes. Rental cars typically come with a Brobizz or similar transponder for automatic payment—confirm with your rental company whether this is pre-installed and how you'll be charged. Cash/card booths exist at major crossings but are less convenient.

From December through February, winter tires (minimum 3mm tread depth) are legally required on all vehicles in Denmark. Snow chains are not commonly used due to Denmark's flat terrain but can be useful if driving to nearby hilly areas in Norway or Sweden. Most rental companies offer winter-equipped vehicles—request these explicitly when booking during cold months. Failure to use proper winter tires can result in fines of 1,500-2,000 DKK ($220-290).

The general speed limit on Danish highways is 130 km/h (about 80 mph), though it drops to 110 km/h on some older sections. In urban areas, expect 50 km/h (31 mph) zones. Speed cameras are widespread and fines are automatic—expect 500-1,500 DKK ($75-220) for exceeding the limit by 10-20 km/h. Denmark uses a point system, and 3 points within 3 years can lead to license suspension for foreign drivers.

Denmark has a well-developed EV charging network, especially around Billund which is near LEGO's headquarters and promotes green initiatives. Major networks like E.ON, Clever, and Tesla Superchargers are available. However, if your rental route includes rural Jutland, charging stations may be spaced 30-50 km apart—plan accordingly. Most rentals come with a charged battery, but confirm the return policy (full charge required or pay-per-use) to avoid extra fees of 200-400 DKK ($30-60).
