Tachograph

A recording device fitted to a goods vehicle that automatically logs driving time, other work, availability, rest and break periods, so that working time compliance can be checked by enforcement officers.

Related: Driving time, Break, Control device
Driving time

The period during which a driver is actually at the controls of a moving vehicle; it is recorded automatically and counted against daily and weekly limits.

Related: Tachograph, Daily driving limit, Break
Daily driving limit

The maximum total time a driver may spend driving within one working day, normally nine hours, extendable to ten hours twice in a week under the EU social rules.

Related: Driving time, Weekly driving limit, Break
Weekly driving limit

The maximum total driving time permitted within a single week, fixed at 56 hours, with a further cap of 90 hours across any two consecutive weeks.

Related: Daily driving limit, Driving time
Break

A period during which a driver performs no driving or other work and which serves to interrupt driving time; after 4.5 hours of driving a break of at least 45 minutes is required.

Related: Driving time, Daily rest period, Tachograph
Daily rest period

The continuous rest a driver must take within each 24-hour period, normally at least 11 hours, reducible to 9 hours a limited number of times per week.

Related: Weekly rest period, Break, Driving time
Weekly rest period

A continuous period of rest taken each week, normally at least 45 hours, which may in certain cases be reduced to 24 hours and compensated later.

Related: Daily rest period, Compensation rest
Compensation rest

Equivalent rest time that must be taken later to make up for a reduced weekly rest period, attached to another rest period of at least nine hours.

Related: Weekly rest period, Daily rest period
Control device

The enforcement tool used to check tachograph records and working time documents, allowing authorities to verify compliance with driving and rest rules.

Related: Tachograph, Driving time
Tachograph record sheet

The paper or digital record on which driving, work, availability and rest periods are registered, serving as evidence of compliance during roadside inspections.

Related: Tachograph, Control device
Speed limiter

A device that restricts the maximum speed of a heavy goods vehicle, typically to 90 km/h, and must be functioning correctly and not tampered with.

Related: Braking system, Tyre tread depth
Braking system

The vehicle system that slows and stops the vehicle, including service brakes, emergency braking and parking brake; it must be inspected and maintained in working order.

Related: Speed limiter, Pre-trip inspection
Tyre tread depth

The minimum legal depth of tread grooves on a tyre, which for heavy vehicles is generally at least 1 mm across the central three-quarters of the tread width.

Related: Tyre pressure, Pre-trip inspection
Tyre pressure

The amount of air inside a tyre; correct pressure ensures grip, fuel efficiency and even wear, and should be checked regularly when tyres are cold.

Related: Tyre tread depth, Pre-trip inspection
Pre-trip inspection

A systematic check of the vehicle's tyres, lights, brakes, mirrors, fluids and load security carried out before departure to confirm roadworthiness.

Related: Braking system, Load security, Tyre pressure
Load security

The practice of arranging and restraining cargo so it cannot shift, fall or affect stability during transport, using straps, bars or other approved restraints.

Related: Load distribution, Pre-trip inspection
Load distribution

Placing cargo so that weight is spread correctly over the axles, respecting maximum axle loads and keeping the vehicle stable and within legal limits.

Related: Load security, Axle load
Axle load

The total weight carried by a single axle of the vehicle, which must not exceed the manufacturer's or legal maximum for that axle.

Related: Load distribution, Maximum authorised mass
Maximum authorised mass

The maximum total weight of a vehicle including its load, as specified by the manufacturer and permitted by law, which must never be exceeded.

Related: Axle load, Load distribution
Defect report

A written record of any fault found on the vehicle that is submitted to the operator so that repairs can be arranged and the vehicle taken out of service if unsafe.

Related: Pre-trip inspection, Braking system
Eco-driving

A driving style using smooth acceleration, early gear changes, steady speeds and anticipation to reduce fuel consumption, emissions and wear on the vehicle.

Related: Anticipation, Speed limiter
Anticipation

Looking ahead and reading the road, traffic and weather to plan actions early, allowing smooth braking and avoidance of sudden manoeuvres.

Related: Eco-driving, Safe following distance
Safe following distance

The gap kept behind the vehicle ahead, allowing enough time to stop safely; in good conditions a minimum of two seconds is recommended, more in rain or darkness.

Related: Anticipation, Stopping distance
Stopping distance

The total distance travelled from the moment a hazard is seen until the vehicle comes to rest, comprising reaction distance plus braking distance.

Related: Safe following distance, Anticipation
Blind spot

The area around a heavy vehicle that the driver cannot see directly or in the mirrors, requiring extra checks and caution when turning or changing lanes.

Related: Mirror adjustment, Vulnerable road user
Mirror adjustment

Correct setting of the vehicle's mirrors to maximise the visible area around the vehicle and minimise blind spots before and during a journey.

Related: Blind spot, Pre-trip inspection
Vulnerable road user

A road user at greater risk of injury in a collision, such as pedestrians, cyclists, motorcyclists and children, who require particular care from professional drivers.

Related: Blind spot, Anticipation
Fatigue

A state of physical or mental tiredness that reduces alertness and reaction time; drivers must plan rest breaks and stop driving when tired.

Related: Break, Daily rest period
Alcohol and drugs

Substances that impair judgement, coordination and reaction time; driving under their influence is prohibited and subject to strict legal limits and penalties.

Related: Fatigue, Reaction time
Reaction time

The delay between perceiving a hazard and beginning to act, typically around one second and increased by fatigue, alcohol or distraction.

Related: Stopping distance, Fatigue
Driving licence category

The classification on a driving licence that states which vehicle types the holder is permitted to drive, such as C for lorries and D for buses.

Related: Driver qualification card, Maximum authorised mass

Emergency braking

A rapid, controlled application of the brakes to avoid a collision, performed while keeping steering control and warning following traffic.

Related: Stopping distance, Braking system
