Prohibited for motor vehicles with more than two wheels and with a permitted gross weight higher than

Prohibitory Signs Sign number: 310

The sign indicates that it is prohibited for motor vehicles with more than two wheels and with a permitted gross weight higher than.

When you see the sign

Check the motor vehicle’s permitted gross weight in the vehicle registration certificate against the weight shown on the sign. If the motor vehicle has more than two wheels and its permitted gross weight is higher than the stated limit, you must not pass the sign; choose an alternative route instead.

Rules

  • The restriction applies to motor vehicles with more than two wheels when their permitted gross weight is higher than the weight shown on the sign.
  • What matters is the motor vehicle’s permitted gross weight in the vehicle registration certificate, not how much it actually weighs or how heavily it is loaded on that trip.
  • If the permitted gross weight is exactly equal to the stated limit, the motor vehicle is not covered by this restriction because the sign applies to weights higher than the limit.
  • The sign can also apply to passenger cars and vans; it is not a restriction that applies only to lorries.
  • Any exceptions or further restrictions may be stated on supplementary plates.

Tips

  • Check the permitted gross weight in the vehicle registration certificate before choosing a route where this sign is indicated.
  • Do not assess the sign based on the vehicle’s current load; an empty vehicle may still be prohibited if its permitted gross weight is too high.
  • Pay particular attention when driving a large SUV, van or motorhome, as these vehicles can also exceed the limit.
  • Follow the alternative-route sign if your vehicle is covered by the restriction.

Common misconceptions

  • !Believing that the sign prohibits only lorries and tractor units.
  • !Using the vehicle’s actual weight on that particular day instead of its permitted gross weight in the vehicle registration certificate.
  • !Believing that a motor vehicle with a permitted gross weight exactly equal to the figure on the sign is prohibited.

Medium

The sign shows 3,5 tonnes. You are driving an empty van with a permitted gross weight of 4 tonnes and an actual weight of 2,6 tonnes. What do you do?

  • AI continue driving because the van's actual weight is lower than the limit.
  • BI choose another road because the van's permitted gross weight exceeds the limit.
  • CI continue driving because the prohibition applies only to lorries and tractor units.
  • DI choose another road because all motor vehicles are prohibited regardless of weight.

Hard

  • AA passenger car with a permitted gross weight of exactly 3,5 tonnes.
  • BAn empty van with a permitted gross weight of 3,6 tonnes.
  • CA tractor unit with a permitted gross weight of exactly 4 tonnes.
  • DA light lorry with a permitted gross weight of 3,8 tonnes.

Theory test tip

Look for the terms “permitted gross weight” and “higher than”. A common trap is an empty van that actually weighs very little but still cannot pass because its permitted gross weight in the vehicle registration certificate exceeds the figure on the sign.

Did you know

The sign is often used where the road standard, surroundings or traffic conditions make it desirable to keep heavier motor vehicles away, while lighter passenger cars and vans can still pass.

Frequently asked questions

Can I pass with an empty van if it actually weighs less than the figure on the sign?

Only if the van’s permitted gross weight is not higher than the figure on the sign. The actual weight and how little cargo you are carrying do not change the assessment.

Does the sign also apply to ordinary passenger cars?

Yes, if the car has more than two wheels and a permitted gross weight higher than the stated limit. The type of vehicle alone is not decisive.

Can I pass if the permitted gross weight is exactly equal to the limit on the sign?

Yes, this sign prohibits motor vehicles with a permitted gross weight higher than the stated weight. An equal weight is therefore not covered, unless another sign or regulation imposes a restriction.

Where can I find the motor vehicle’s permitted gross weight?

It is stated in the vehicle registration certificate and may also be found in the vehicle information. Do not use the unladen weight or the weight you assume the vehicle has right now.
