Prohibited for all tractors and motorised equipment designed for a speed of less than 40 km/h
The sign indicates that it is prohibited for all tractors and motorised equipment designed for a speed of less than 40 km/h.
When you see the sign
If you are driving a tractor, you must not pass the sign, regardless of the speed the tractor is designed for. If you are driving a motorised implement, you must choose another route if the vehicle is designed for a speed of less than 40 km/h, unless a supplementary plate indicates a relevant exception.
Rules
- The prohibition applies to all tractors, including tractors designed for 40 km/h or more.
- For motorised implements, the prohibition only applies when the vehicle is designed for a speed of less than 40 km/h.
- It is the vehicle’s designed speed, not the speed at which it is travelling when it reaches the sign, that determines whether a motorised implement is covered.
- Other vehicles, such as passenger cars, motorcycles and lorries, are not covered by this sign alone.
- A supplementary plate may specify when the prohibition applies or indicate an exception.
Tips
- Check the vehicle’s registration details if you are unsure of its vehicle type or designed speed.
- Plan an alternative route in advance when driving a tractor or a slow-moving motorised implement.
- Look for supplementary plates that may indicate a time restriction, a section of road or an exception.
- Do not assume that you can avoid the prohibition by driving faster; the designed speed does not change with the actual speed.
Common misconceptions
- Believing that the sign only applies to tractors designed for less than 40 km/h. The speed specification in the text only applies to motorised implements.
- Interpreting the sign as a prohibition on all motor vehicles or all vehicles.
- Believing that a motorised implement is permitted as long as it is actually travelling at 40 km/h; the designed speed is what matters.
Test yourself
Easy
What does this sign mean?
- AAll vehicles are prohibited, regardless of vehicle type and designed speed.
- BAll tractors and all types of motorised equipment are prohibited.
- CAll motor vehicles, except small electric motor vehicles, are prohibited.
- DAll tractors and motorised equipment designed for less than 40 km/t are prohibited.
Medium
You are driving a passenger car and encounter this sign without a supplementary sign. What should you do?
- AStop because the sign prohibits travelling with all vehicles.
- BContinue only if the car maintains at least 40 km/t.
- CContinue if this is otherwise lawful and safe.
- DTurn around because the sign prohibits travelling with all motor vehicles.
Hard
A tractor designed for 50 km/t and motorised equipment designed for exactly 40 km/t are approaching this sign. Both are travelling at 30 km/t. Who may drive past the sign?
- ANeither vehicle may drive past the sign.
- BOnly the motorised equipment may drive past the sign.
- COnly the tractor may drive past the sign.
- DBoth vehicles may drive past the sign.
Theory test tip
A typical trap is the placement of the phrase «designed for a speed of less than 40 km/h». It only limits which motorised implements are covered; all tractors are prohibited.
Did you know
The sign is used, among other places, where tractors and slow-moving motorised implements could create dangerous speed differences or be poorly suited to the road’s standard and traffic flow.
Frequently asked questions
Can a tractor designed for 50 km/h pass the sign?
No. The prohibition applies to all tractors, regardless of the tractor’s designed speed.
Can a motorised implement designed for exactly 40 km/h pass?
Yes, the sign alone prohibits motorised implements designed for a speed of less than 40 km/h. Exactly 40 km/h is not less than 40 km/h, but other signs and rules may still restrict access.
Does the prohibition apply to an ordinary passenger car travelling at less than 40 km/h?
No. The sign applies to the vehicle type and the motorised implement’s designed speed, not to how slowly a passenger car is actually travelling.
What should I do if there is a supplementary plate below the sign?
You must read the main sign and the supplementary plate together. The supplementary plate may, among other things, limit the period of validity or indicate an exception.
