Car Hire at Brooks Station, Washington D.C.

Your UK full driving licence is valid for up to 12 months in the USA, but an International Driving Permit (IDP) is strongly recommended. Rental companies frequently request the IDP as standard practice, and you'll need one if stopped by police. Obtain your IDP from the AA or RAC before departure—it costs around £5.50 and takes one day. Without it, you risk being refused vehicle collection.

Most toll roads on the East Coast use E-ZPass electronic tolling—no cash or card payments at most gantries. If you're renting, ask your hire company whether their vehicles have an E-ZPass transponder built in; if so, tolls are added to your rental bill (typically a small daily surcharge of $3-4). Without one, you can expect a bill sent to the rental company's address, incurring significant admin fees of $20-50 on top of the toll itself. For occasional use, consider buying a portable E-ZPass at service stations for around $35 preloaded.

Yes—downtown parking routinely costs $25-40 per day in garages and $2-4 per hour at meters. A crucial trap for visitors is residential permit parking zones: streets marked with signs saying 'RPP' require a District of Columbia parking permit that tourists cannot obtain. Park in these zones and you'll receive a $75 ticket within hours. Your hire company's GPS or a parking app like ParkMobile is essential to avoid fines. Hotel parking, where available, typically runs an eye-watering $45-60 per night.

Yes, virtually all US rental companies charge a 'young driver fee' for drivers under 25. Expect to pay approximately $25-35 per day on top of the standard rental rate. This surcharge applies until your 25th birthday—you cannot avoid it. Some UK credit cards include bundled collision damage waiver insurance that may cover this surcharge, but check your policy details carefully before relying on it. Budget an additional £400-600 for this surcharge on a two-week rental.

Washington D.C. experiences an average of 15-20 inches of snow annually, primarily from December to March. While major highways are salted and ploughed promptly, side streets can become icy and hazardous. Snow chains are rarely used in the D.C. area and are impractical with standard hire cars. Instead, carry an ice scraper, flashlight, and ensure your hire vehicle has front-wheel drive or four-wheel drive if travelling in winter months. If a significant snowstorm is forecast, consider postponing non-essential journeys—Interstate 95 becomes notoriously dangerous with jackknifed trucks and multi-hour delays.

Your UK credit card's collision damage waiver typically provides secondary coverage only, meaning you must pay for damage first and claim reimbursement later—a process that can take months and may not cover all damage types. For peace of mind, accept the rental company's full collision damage waiver (CDW/LDW) at $20-35 per day. This is particularly advisable in D.C., where minor parking dings are common and the city's aggressive traffic enforcement means you're frequently navigating tight spaces. Check whether your annual travel insurance provides primary CDW—it can halve your insurance expenditure.
