Car Hire in the United Kingdom

Driving in the United Kingdom: Essential Rules

• Side of the road: the UK drives on the left, with the steering wheel on the right-hand side of the car — the opposite convention to most of mainland Europe and North America, so allow a little extra time to adjust, particularly on your first roundabout.
• Roundabouts: give way to traffic already on the roundabout, which in the UK approaches from your right, not your left.
• Alcohol limit — this varies within the UK: the limit in England, Wales, and Northern Ireland is 80 mg of alcohol per 100 ml of blood (35 micrograms per 100 ml of breath). Scotland applies a stricter limit of 50 mg per 100 ml of blood (22 micrograms per 100 ml of breath). If your trip crosses between Scotland and the rest of the UK, drive to the stricter Scottish limit throughout to stay safely within the law everywhere. A change to align England and Wales with Scotland's lower limit has been proposed by the government but was not yet in force as of the most recent confirmation, so it is worth checking the current position closer to your travel date.
• Mobile phones: handheld use of a phone while driving is banned, covering calls, texts, photos, and any other interaction with the handset, not only phone calls. A hands-free set, set up before you start driving, is the only legal option for calls on the move.
• Headlights: dipped headlights are required at night in built-up areas and on unlit roads, and front and rear fog lights should be used when visibility drops below around 100 metres.
• Seatbelts and children: seatbelts are mandatory in all seats fitted with one. Children generally need an appropriate child seat or booster until they are 135 cm tall or turn 12, whichever happens first.
• Toll roads and crossings: most of the UK's road network is toll-free, but a small number of roads and river crossings charge a toll, including the Dartford Crossing east of London, the M6 Toll near Birmingham, and the Mersey Gateway near Liverpool. Some of these, including the Dartford Crossing, have no barrier or on-the-spot payment option at all — payment is made online or by app within a set window after crossing, and missing that window results in a penalty charge. Scotland abolished all its road tolls in 2008 and remains toll-free.
• London Congestion Charge and low-emission zones: driving into central London incurs a daily Congestion Charge, and much of Greater London falls within the Ultra Low Emission Zone (ULEZ), which charges non-compliant vehicles separately from the Congestion Charge itself. Several other UK cities, including Birmingham and Bristol, operate their own Clean Air Zones. Confirm your hire vehicle's compliance and how any charges are billed before driving into any city centre, as these schemes are camera-enforced with no barrier to alert you at the boundary.
• Driving licence: most visitors can drive in the UK on a full, valid licence from their home country for a limited period without needing anything further, though requirements can depend on where the licence was issued and how it's printed. Confirm with your supplier whether your licence is sufficient on its own or whether an International Driving Permit is recommended.
• Documents to carry: keep your driving licence, passport or photo ID, and the vehicle's registration and insurance documents with you at all times, as these can be requested during a routine stop.

Many urban roads, particularly residential streets, are signed to a lower 20 mph limit, and the national speed limit (indicated by a plain white circular sign with a black diagonal stripe) can vary depending on the road and vehicle type. Always follow posted signage over the general figures shown here.

United Kingdom Car Hire Insurance

Every car hire booked through eCarBookers in the United Kingdom includes the supplier's standard collision damage waiver (CDW) in the basic rate. Standard CDW carries an excess — the amount you would be responsible for in the event of damage. Excess amounts vary by supplier and vehicle class, and the exact figure is displayed clearly before you confirm your booking, so there are no surprises at the desk.

If you prefer to drive with no excess at all, fully comprehensive zero-excess cover is available directly from your supplier when you collect the car in the UK. The cover comes from the hire company itself, not from a third-party insurer — so there is no separate policy, no paying the excess upfront, and no reimbursement claim to file once it has been added. Because your booking confirmation shows the standard excess that applies, you arrive knowing exactly what the cover replaces.

It is worth noting that certain situations fall outside standard CDW cover across the car hire industry. Tyres, glass, underbody damage, lost or damaged keys, and a flat battery caused by driver error are typically not covered and may result in a separate charge if they occur. These situations are uncommon in everyday driving, but it is good practice to check your booking confirmation for the specific cover terms applicable to your hire, as scope can vary by supplier.

If your trip includes taking the car onto the continent, whether by ferry or the Channel Tunnel, this is not something to assume is automatically covered — confirm with your supplier well in advance whether your hire car is permitted to leave the UK at all, and if so, what additional documentation or cover applies once you're driving in mainland Europe.

Manchester and Birmingham are well placed for the Peak District and the Midlands, and Belfast is the main gateway to the Causeway Coast in Northern Ireland. Dedicated city and airport pages for UK locations are planned as the network expands; check back for direct links as those pages go live.
