Signs and markings
Sign questions test whether you read a restriction as it applies to your combination: weight, height, length and the vehicle-with-trailer symbol.
Sign families
- Prohibition: circular with red border (no entry, weight limit, trailer prohibited).
- Mandatory: blue circle (direction, minimum speed, snow chains).
- Warning: red triangle (uneven road, tunnel, falling rocks).
- Priority: yellow diamond for forkjørsvei, the inverted triangle for give way.
Markings
- Centre lines are yellow; edge and lane lines are white.
- A solid line (sperrelinje) must not be crossed; broken lines permit overtaking when it is safe.
- Arrows and hatched areas channel traffic; do not drive on hatched markings.
- Supplementary plates give distance, direction or a vehicle class.
Reading a restriction correctly
Weight signs state the permitted actual total weight in tonnes, not the registered weight. Height signs give maximum height including load. A sign showing a car plus trailer means the ban applies to combinations, not to a solo tractor unit.
Worked example
A bridge carries the sign 7.5 t with no supplementary plate. Your tractor unit is registered at 7,500 kg but you are loaded to 9,200 kg. You may not cross: the sign limits actual total weight. You reload, redistribute or reroute; an omkjøring sign is not an exception for you.
Traps that cost marks
- Forgetting that the height and length of the load count, not just the vehicle.
- Treating hatched markings as an extra lane.
- Believing a gjennomkjøring forbudt sign bars a delivery when the destination lies inside the zone.
