Support Materials

All material for this course will be facilitated via a Moodle Page. Delegates are welcome to bring their laptops. Material will be made available via the Moodle page prior to each day of training. It is advised that attendees are familiar with DN-REQ-03034 and DN-REQ-03079.

Course Duration

This programme will consist of 2 and a half training days across a two week period followed by an assessment. The assessment day will consist of an online afternoon examination. Further CPD hours can be recorded for study hours.


There will be a multiple-choice examination on DAY 3 to assess your knowledge against the learning outcomes with a 70% pass rate (21 out of 30). Special arrangements can be made should delegates wish to re-sit the examination. The course workshop outputs will also be formally assessed by the facilitators.


On successful completion of this course, delegates will be awarded with a Special Purpose Award from TU Dublin (Technological University Dublin) at Level 8, worth 1 ECTS credit.

Who Should Attend?

The course is aimed at Engineers involved in the design, specification, installation, supervision, certification, maintenance and road safety reviews of Vehicle Restraint Systems. It is anticipated that successful completion of this course will be a mandatory requirement in the future for designers certifying Vehicle Restraint System installations or repairs on national roads.
