Traffic control and traffic flow describes how different authorities and personnel regulate traffic to ensure safety and efficient movement on Norwegian roads.
For a full overview of the current rules, see Laws and regulations.
Authorities involved in traffic control
In Norway several actors can direct traffic or carry out checks to maintain order, safety and flow:
| Authority | Role | Legal basis |
|---|---|---|
| Police | Manually direct traffic, enforce rules and issue orders | Road Traffic Act and local police regulations |
| Customs | Vehicle checks at border crossings | Customs Act |
| Norwegian Public Roads Administration | Inspection, regulation, road work zones and controls | Road Traffic Act and vehicle regulations |
| Road work personnel | Temporary signing, stopping and directing at work zones | Regulation on execution of road works |
Hand signal: arm raised
When traffic must be guided past obstacles or where there are no lights, hand signals are used. The most common is arm raised (amber signal) by police or construction personnel:
| Signal | Meaning |
|---|---|
| Arm raised (amber) | Stop or slow down; prepare for further directions |
| Arm pointing horizontally (red) | Drive in the indicated direction when told |
| Both arms towards lower back | Stop traffic in both directions |
See also Give‑way and roundabouts for how hand signals overrule other rules.
Measures for efficient flow
Traffic control is not only about stopping, but also about optimising flow in different zones:
- Traffic lights and variable signs for dynamic speed adjustment
- Manual directing at events and construction
- Use of temporary roads and detours during road works
- Vehicle classification and lane control at borders and toll stations
For details on enforcement and sanctions, see Laws and regulations. For priority between lights, signs and hand signals, see Signals vs signs in traffic.
Summary
A good understanding of traffic control and traffic flow is essential for safe driving. Knowing the signals, roles and rules ensures you act correctly and contribute to smooth traffic.
