Half of all HGVs inspected in roadside checks by RSA Vehicle Inspectors and An Garda Síochána between 2018-2020 were found to have a roadworthiness defect.
An average of 9,500 HGVs were inspected each year over each of the last three years, with approximately 20 per cent found to have minor defects, 25 per cent major defects and four per cent dangerous defects.
The RSA says the most common dangerous and major defects detected includes excessively worn or damaged tyres, faulty lighting systems, excessively worn braking components and defective anti-lock braking systems, which are designed to help drivers maintain steering control in emergency situations.
Sam Waide, CEO of the RSA is urging HGV drivers to carry out daily walk around checks to look for defects before setting out on a journey.
He said: “As the owner, user or driver of a commercial vehicle you are legally required to ensure that a walk around check of the vehicle is carried out once in every 24-hour period before it is used on a public road.
“They are essential in preventing potentially dangerous vehicles from causing serious or possibly fatal collisions on the road.
“The most common dangerous defects detected include excessively worn or damaged tyres and faulty brake lights.
“Tyres are a vehicle’s only contact with the road and excessively worn or damaged tyres potentially reduce grip and the vehicle’s ability to stop safely.
“Vehicles with faulty stop lights have the potential to cause a serious collision as other road users will not be aware that the brakes have been applied and the vehicle is slowing down or coming to a stop.”
The RSA is also reminding HGV operators that Commercial Vehicle Roadworthiness Testing (CVRT) has been deemed an essential service during the ongoing Covid-19 restrictions.
