Reaction distance formula
Reaction distance in metres equals speed in km/h divided by ten, multiplied by three. At 50 km/h this gives 15 m before the brake even begins to act.
Braking distance formula
Braking distance in metres is approximately (speed in km/h divided by ten) squared. At 100 km/h on dry asphalt that is about 100 m.
Aquaplaning risk threshold
Standing water deeper than roughly 5 mm can lift the tyre off the road from about 80 km/h. Ease off the throttle and avoid sudden braking or steering.
Two-second rule
Keep at least two seconds behind the vehicle ahead in dry conditions. Double the gap in rain and extend it to roughly ten times on ice.
Rettungsgasse formation
As soon as traffic slows to walking pace, form a rescue lane between the leftmost lane and the one next to it. Emergency vehicles use it to reach the scene.
Warning triangle distances
Place the triangle about 50 m behind the vehicle on country roads and 100 m on motorways. Behind a bend or crest, place it before the hazard becomes visible.
Winter tyre obligation
Winter tyres are required in snow, slush, ice, and frost. The legal minimum tread is 1.6 mm, but 3 mm is recommended for wet grip.
Probation period alcohol limit
During the probation period (Probezeit) and for drivers under 21, the alcohol limit is 0.0 per mille. Any alcohol is an offence.
Rechts vor links
At junctions without signs or signals, the vehicle coming from the right has priority. This rule does not apply when leaving a field, property, or pedestrian zone.
Leaving a field entrance
A tractor leaving a field, farm track, or property onto a public road must yield to all traffic. The right-before-left rule does not apply here.
Hierarchy of traffic rules
Police signals override traffic lights, which override traffic signs, which override the right-before-left rule. This order is fixed and applies everywhere.
Turning left priority
A vehicle turning left must yield to oncoming traffic going straight on and to pedestrians and cyclists crossing the road it is entering.
Danger sign placement
Triangular warning signs stand 150–250 m before the hazard outside built-up areas and 50–150 m inside built-up areas.
Stop sign obligation
At a Stop sign the vehicle must come to a complete stop at the stop line, even when the road appears clear, before giving way.
Amber traffic light
Amber alone means stop unless stopping would be unsafe. Red plus amber together announces the coming green phase.
Continuous white line
A continuous white line must not be crossed. A broken line may be crossed when it is safe and does not endanger other traffic.
Speed and fuel consumption
Air resistance grows with the square of speed, so fuel use rises about 30 % at 130 km/h compared with 100 km/h.
Tyre pressure and fuel
A tyre pressure deficit of 0.5 bar typically adds 2–3 % fuel consumption and increases tyre wear. Check pressure when tyres are cold.
Engine idling cost
Idling burns 0.5–1.0 litres per hour. Switch the engine off at stops expected to last longer than about 20 seconds.
Schubabschaltung
When coasting in gear with the throttle released, the engine cut-off stops fuel injection entirely. The vehicle uses zero fuel while rolling.
Differential lock use
Engage the differential lock only at low speed on loose ground. Disengage it before turning on firm ground to avoid transmission wind-up.
Power take-off speeds
Standard PTO speeds are 540 rpm at 540 engine rpm and 1000 rpm at 1000 engine rpm. Match the implement's rated speed to avoid damage.
Front axle minimum load
The front-axle load must be at least 20 % of the tractor's total mass for safe steering. Ballast weights adjust the distribution.
Hydraulic injection hazard
Hydraulic systems run at 180–200 bar. A leaking hose can inject fluid under the skin; never check for leaks with the hand.
Tempo-100 trailer rule
A braked trailer may be driven at 100 km/h only with a tempo-100 approval sticker and a tractor approved for that combination.
Lashing force calculation
The total securing force must equal the load weight times the acceleration factor: 0.8 forward, 0.5 sideways and rearward, per VDI 2700.
Rear projection marking
Loads projecting more than 1 m beyond the rear must carry a red flag or panel by day and a red light by night.
Trailer tyre replacement
Trailer tyres age faster than tractor tyres. Replace them at about six years regardless of tread depth and check pressure when cold.
Criminal alcohol threshold
From 1.1 per mille blood alcohol the offence becomes criminal (Trunkenheit im Verkehr). Between 0.5 and 1.1 it is an administrative offence.
Chest compression rate
In adult first aid, compress the chest at 100–120 per minute to a depth of 5–6 cm. Call 112 and continue until help arrives.
Recovery position
Place an unconscious but breathing casualty in the recovery position on the side. Do not move a casualty with suspected spinal injury unless in immediate danger.
Microsleep countermeasure
A 15–20 minute nap or a 20-minute coffee break restores alertness better than fresh air or loud music. Tiredness causes microsleep.
