Motorway speed limit, heavy goods vehicle
A goods vehicle over 3,500 kg design gross weight is limited to 90 km/h on an Irish motorway, unless a lower limit is posted.
National road goods vehicle limit
Goods vehicles over 3,500 kg are restricted to 80 km/h on national roads, and the same 80 km/h applies on regional and local roads.
Continuous white centre line
Crossing it is prohibited except to avoid an obstruction or in an emergency; where lines are doubled, the nearer line's rule governs.
Yellow box junction rule
Do not enter unless the exit is clear; the only exception is turning right when blocked solely by oncoming traffic or other right-turning vehicles.
Solid yellow kerb line
Marks a prohibition on parking at the times shown on the nearby plate; broken yellow lines restrict parking only during the periods stated.
Irish warning sign shape
Warning signs are yellow diamonds with a black border; prohibitions are red-bordered circles and mandatory instructions are blue circles.
Parking near a junction
Parking within 5 metres of a road junction is prohibited, and within 15 metres on the approach side of a pedestrian crossing.
Hard shoulder status
The area beyond a broken yellow edge line is a hard shoulder, not a running lane; stopping is allowed only in an emergency or where signed.
HGV minimum tread depth
Goods vehicles over 3,500 kg need at least 1.0 mm tread across the central three-quarters, around the whole circumference, with no cuts exposing cord.
Brake efficiency legal minimum
Service brake must achieve 50 percent efficiency, secondary or parking brake 25 percent, and the parking brake must hold on a 16 percent gradient.
Daily walkaround check scope
Check lights, tyres and pressures, wheel nut indicators, air pressure build-up, leaks, load security, mirrors, wipers, washers and the horn before each duty.
Load projection marking
A load projecting more than 1 metre beyond the rear of the vehicle must be clearly marked so following traffic is warned.
Maximum vehicle height
The general maximum height for a vehicle in Ireland is 4.65 metres unless a permit applies; bridge heights are signed in metres and feet and inches.
Fog light use rule
Front or rear fog lights may be used only in fog or falling snow, and must be switched off when visibility improves to avoid dazzling others.
CVRT test age threshold
A vehicle first registered more than 4 years ago requires an annual roadworthiness test, with a valid CVRT certificate and insurance disc displayed.
Air brake warning defect
Excessive air loss on a full brake application, or a warning that continues after pressure builds, makes the vehicle unroadworthy until repaired.
Tyre pressure checking rule
Pressures are set and checked when tyres are cold; a hot reading will be higher and should not be used to reduce pressure.
Two-second following rule
Maintain at least a two-second gap in dry conditions, double it to four seconds in rain, and increase it greatly on ice or snow.
Professional driver alcohol limit
Learner, novice and professional drivers are limited to 20 mg of alcohol per 100 ml of blood, lower than the 50 mg limit for other drivers.
Stopping distance at 80 km/h
Thinking distance plus braking distance totals roughly 53 metres on a dry road; braking distance increases with the square of speed.
Fatigue break guidance
Plan a break of at least 15 minutes every two hours and take a short sleep if sleepy; fresh air and loud music do not restore alertness.
Moving off observation order
Check mirrors, signal if needed, look over the shoulder into the blind spot, then move off only when the way is clear.
Left turn lorry hazard
A lorry may swing out before turning left, and cyclists or pedestrians can be on the inside; check the left mirror and blind spot throughout the turn.
Safe speed definition
A safe speed allows the vehicle to stop within the distance seen to be clear ahead, taking account of road, weather and load.
Single-track road passing places
Where vehicles meet on a single-track road, the vehicle nearest a passing place should reverse into it so the other can proceed.
Daily driving limit
EU rules allow a maximum of 9 hours driving per day, extendable to 10 hours no more than twice in a week.
Weekly driving limits
A driver may not exceed 56 hours driving in any week, nor 90 hours in any two consecutive weeks.
Break after 4.5 hours driving
A break of at least 45 minutes is required after 4 hours 30 minutes driving, splittable into 15 minutes then 30 minutes in that order.
Reduced daily rest
Daily rest may be reduced from 11 to 9 hours no more than three times between weekly rests; a split daily rest is 3 hours plus 9 hours.
Weekly rest and compensation
Weekly rest is at least 45 hours, reducible to 24 hours if the reduction is compensated in one block before the end of the third following week.
Tachograph record retention
Records must be kept for at least 12 months, and a driver must produce the current day plus the previous 28 days at a roadside check.
Driver CPC periodic training
A professional driver completes 35 hours of periodic training in each five-year cycle and carries a Driver Qualification Card while driving.
