What is Kerb Weight?
Kerb weight is the total weight of your vehicle as it sits ready to drive, including fuel, oil, coolant, and all standard equipment. It's different from the actual weight of the car's body alone. Understanding your vehicle's kerb weight is important for various practical reasons including toll bridges, ferry crossings, and determining whether your driving licence category permits you to drive the vehicle. A kerb weight check by registration gives you the exact specifications for your car model and variant.
Kerb Weight vs Gross Vehicle Weight Rating
These two terms are often confused but represent different measurements. Kerb weight is the vehicle's actual weight when empty and ready to drive. Gross Vehicle Weight Rating (GVWR) is the maximum safe weight including the car, passengers, cargo, and fuel. The difference between these figures tells you the maximum payload your vehicle can safely carry. For example, a car with a kerb weight of 1,200kg and GVWR of 1,500kg can carry 300kg of additional load. Checking both figures ensures you stay within safe operating limits and comply with any legal requirements.
Why Kerb Weight Matters for UK Drivers
Knowing your car's kerb weight has several practical implications:
- Toll bridges and ferries - Some crossings charge based on vehicle weight; you need accurate figures to calculate costs
- Payload capacity - Determines how much luggage, passengers, and equipment you can safely carry
- Driving licence categories - Your licence category may restrict vehicles exceeding certain weight limits (3.5 tonnes for standard cars)
- Fuel efficiency - Heavier vehicles consume more fuel, affecting running costs
- Parking restrictions - Some car parks have weight limits for structural safety
How to Check Your Car's Kerb Weight by Registration
The simplest method is to use an online car check service where you enter your registration number. Your vehicle's handbook contains detailed specifications including kerb weight, and the DVLA records also hold this information. Most manufacturer websites display kerb weight in their technical specifications for each model and engine variant.
Using Kerb Weight Information Safely
Never exceed your vehicle's GVWR by overloading it with passengers or cargo. Overloading affects handling, braking distance, and tyre wear. It can also invalidate your insurance if an accident occurs whilst the vehicle is overloaded. Always verify both kerb weight and GVWR when planning journeys with heavy luggage or equipment.
