Vehicle Restraint Systems Design


2-day course

CPD Credit: 14 hours, C1 / C2

Course Overview

Upon completion of the training course, attendees will have developed skills in design, installation and maintenance of Vehicle Restraint Systems (VRS), including safety barrier and parapet systems, in accordance with relevant standards (IS EN 1317, DN-REQ-03034, DN-REQ-03079, DN-GE-03036 and CC-SPW-00400).

  • Designing to 03034
  • Workshops
  • Overview of Standard and Risk Assessment Process
  • Workshop on Assessing the need for VRS
  • Detailed Design (VRS PDR) including innovations
  • Workshop Examples
  • SAVeRS - Workshop
  • Innovations
  • Specification Series 400
  • Installation Process
  • Maintenance, Inspection and Repair of VRS
  • End of Course Test

Support Materials

All slides and training materials will be provided for you on the day. It is advised that attendees are familiar with DN-REQ-03034 and DN-REQ-03079


There will be a multiple-choice examination at the end of day 2 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.
