Brake tests for heavy-duty vehicles

From 2025 to 2028
The Irish authorities are exploring whether the braking performance of heavy vehicles can be predicted more accurately through extrapolation, as current tests do not always reflect real-world braking behaviour. TML supports this research with data analysis and expertise in road safety and European regulation.
Reliable brake testing is essential for the safety of heavy vehicles, yet in practice the current method can fall short. Roller Brake Testers measure mainly under light conditions, meaning hidden defects or abnormal on-road braking behaviour are not always detected, creating uncertainty for inspectors and risks out on the road.
The Irish Road Safety Authority is therefore examining whether extrapolation can provide smarter insight: can a limited set of measurements still accurately predict braking performance at higher pressures or under load? The project reviews international practices, analyses alternative testing approaches, and evaluates which method is most reliable, feasible, and safe for the Irish context.
TML strengthens the project team with expertise in data analysis, road safety, and European regulation. We analyse the available vehicle and test data, contribute to the assessment of extrapolation methods, and bring a broader European perspective to the study.
