Norway Professional Driver Competence (YSK) cheat sheet

Rational driving rests on three pillars: anticipation (read the road 12-15 seconds ahead), smoothness (no harsh braking or acceleration), and economy (engine in the green torque band, typically 1,200-1,500 rpm for heavy diesels).

Kinetic energy rises with the square of speed: doubling speed quadruples braking distance. A 40-tonne combination at 80 km/h carries roughly 9.9 MJ of kinetic energy versus 2.5 MJ at 40 km/h.

Reaction distance in metres equals speed in km/h divided by 10, multiplied by 3 (about 1 second reaction). At 80 km/h that is roughly 24 m before the brakes even engage.

Braking distance scales with the square of speed divided by twice the deceleration: d = v²/(2a). At 80 km/h (22.2 m/s) and a = 5 m/s², the stopping distance from brake application is about 49 m.

Total stopping distance = reaction distance + braking distance. Wet or icy roads can cut achievable deceleration by 50-70%, so treat the safety margin as a multiplier, not a fixed gap.

Anticipatory driving rule: lift off early rather than brake late. Coasting to a lower speed uses zero fuel, whereas braking converts already-spent fuel into heat.

Use retarder, exhaust brake, or engine braking on long descents to keep service brakes cool; brake fade begins when drum or disc temperatures exceed roughly 200-300 °C.

Eco-rolling and cruise control reduce fuel use on motorways, but disable cruise control in rain, fog, or on winding roads where speed must vary continuously.

Driving licence categories for goods: C1 up to 7.5 t, C above 3.5 t, C1E and CE for trailers. Driver CPC (yrkessjåførkompetanse) is required for professional driving in categories C and D.

ADR applies from the thresholds in the dangerous goods rules: flammable liquids and solids generally from 1,000 litres/kg per transport unit, with exemptions for limited quantities and excepted quantities.

ADR transport document must state UN number, proper shipping name, class, packing group, number and description of packages, total quantity, consignor and consignee.

ADR orange plates: plain orange plate front and rear for most loads; for tank transport the plates carry the hazard identification number on top and UN number below.

Vehicle weights: standard semi-trailer combination max 40 t in Norway; modular combinations (vogntog) up to 60 t on designated roads, with length up to 25.25 m.

Driving bans and weekend restrictions apply to heavy goods vehicles in several European countries; Norway has no general weekend ban but local and tunnel restrictions exist.

Cabotage: three operations within seven days after an international delivery, then a cooling-off period before further cabotage in the same country.

Speed limits for heavy goods vehicles in Norway: generally 80 km/h on motorways unless signed otherwise; lower limits apply in tunnels and built-up areas.

Fatigue risk peaks between 02:00-06:00 and 14:00-16:00; a 15-20 minute nap or a caffeine dose followed by a short nap restores alertness faster than cold air or loud music.

Alcohol limit in Norway is 0.02% blood alcohol (0.2 g/L); any measurable level above that is a criminal offence, and a single unit can exceed it for some drivers.

Load securing and tyre condition are checked at roadside inspections; defective tyres, brakes, or lights are the most common causes of prohibition notices.

Environmental zones and toll rings: Norwegian toll charges vary by fuel type and Euro emission class; Euro VI and zero-emission vehicles pay reduced or zero rates in many schemes.

Defensive following distance: the three-second rule at minimum, doubled in rain and tripled on ice or snow; heavy vehicles need additional distance because of longer stopping distances.

Customer service in logistics includes accurate ETA communication, proof of delivery with signature or photo, and handling of temperature-controlled or fragile goods.

Waste and spill procedures: absorbent material, containment, and reporting to emergency services for any fuel or chemical spill; environmental damage can trigger liability.

Personal protective equipment: high-visibility vest, safety shoes, gloves, and hearing protection are standard for loading and unloading operations.

Pre-trip inspection covers tyres (tread depth at least 1.6 mm for cars, 1.0 mm for heavy goods vehicles in Norway, plus sidewall condition), lights, brakes, fluids, mirrors, and load security.

Air brake system: pressure builds to 8-10 bar; a warning sounds below about 5.5 bar, and spring brakes apply automatically when pressure drops to the safety threshold (around 4.5 bar).

Tachograph and speed limiter: goods vehicles over 3.5 t must have a speed limiter set at 90 km/h; the tachograph records speed, distance, and driver activity.

Diesel particulate filter (DPF) regeneration requires periodic higher exhaust temperature; short urban runs can clog it, so follow the manufacturer's regeneration procedure.

Coolant and oil checks must be done with the engine cold or per manufacturer instructions; hot coolant systems are pressurised and can cause severe burns.

Tyre pressure affects fuel consumption and handling: under-inflation by 20% can increase fuel use and heat build-up, risking blowouts on long descents.

ABS and EBS: ABS prevents wheel lock under braking; EBS adds electronic brake distribution and stability control, but neither replaces safe following distance.

Wheel and tyre checks after the first 50-100 km of a journey catch loose wheel nuts and settling loads before they become a hazard.

Load securing standard: the cargo must be secured so it cannot shift, tip, or fall. The required lashing force is calculated from the cargo mass and the acceleration forces (forward 0.8 g, sideways 0.5 g, rearward 0.5 g).

Number of lashings: for a given cargo mass, the required lashing capacity (LC) is at least the cargo weight times the acceleration factor divided by the lashing angle factor (typically 0.5-0.7 for angled straps).

Load distribution: axle loads must not exceed the manufacturer's plated limits; the load should be centred and low to keep the centre of gravity low and improve stability.

Positive fit (form-fit) loading is the strongest method: cargo placed against headboard and side walls with no gaps needs fewer lashings than loose cargo.

Straps must be rated and marked with their lashing capacity (LC) in daN; a 50 mm strap typically has LC around 2,500 daN, and damaged straps must be discarded.

Anti-slip mats increase friction and reduce the number of lashings required; wet or icy loading surfaces reduce friction and demand more securing.

Hazardous loads require segregation, correct placarding, and a transport document; incompatible classes must not be loaded together without segregation rules.

After loading, check that doors, tail lifts, and curtains are closed and locked, and that the load is visible or documented for inspection.

Daily driving limit: 9 hours, extendable to 10 hours twice per week. Weekly limit: 56 hours. Two-week limit: 90 hours.

Breaks: after 4.5 hours of driving, a 45-minute break (or split into 15 minutes then 30 minutes) is required before driving again.

Daily rest: 11 hours, reducible to 9 hours up to three times between weekly rests. Weekly rest: 45 hours, reducible to 24 hours with compensation.

Tachograph: digital tachograph records driver card data; manual entries must be made for activities outside the vehicle (other work, availability, rest).

Driver card must be inserted at the start of the shift and removed at the end; card misuse or failure to record is an offence with fines.

Working time directive for mobile workers: maximum average 48 hours per week over four months, with night work limits and minimum rest periods.

Enforcement: roadside checks compare tachograph records with the driver's declarations; infringements are graded minor, serious, or very serious, affecting the operator's licence.

Record keeping: tachograph data must be retained by the operator for at least one year (two years for some records) and made available to inspectors.

The tachograph mode switch has four positions: driving (automatically recorded when moving), other work, availability, and rest.

Availability mode applies when the driver is waiting but must remain available, for example on a ferry crossing or at a loading bay.

A ferry crossing can count as a break or rest if the driver has access to a bunk or reclining seat; otherwise it counts as availability.

Digital tachograph data download: driver card every 28 days, vehicle unit every 90 days, by the operator.

Manual entries must be made at the start of the shift for any work done before inserting the card, and at the end for work after removal.

Infringement examples: exceeding 4.5 hours driving without a break, insufficient daily rest, missing weekly rest, and failure to make manual entries.

Working conditions: the driver is entitled to a safe vehicle, adequate rest facilities, and protection from excessive working hours under the Working Environment Act.

Multi-manning: with two drivers, each must take a 30-minute break after 4.5 hours, and daily rest can be taken in a moving vehicle if it has a bunk.

Weekly rest must start no later than six 24-hour periods after the end of the previous weekly rest period.

A reduced weekly rest of at least 24 hours must be compensated by an equivalent period attached to another rest period within three weeks.

The 12-day rule: under certain conditions, weekly rest can be postponed for one week, allowing 12 consecutive days of work before a normal weekly rest.

Driving time is recorded automatically when the vehicle moves; any movement, even in a yard, counts as driving time.

Other work includes loading, unloading, paperwork, vehicle checks, and cleaning; it must be recorded as such, not as rest or availability.

Rest means the driver is free to dispose of their time; being on call at the depot is not rest.

Tachograph printouts can be used when the card is defective; the driver must annotate and keep them for inspection.

Penalties for tachograph manipulation include fines, licence suspension, and operator licence consequences; the operator is responsible for compliance.
