<p>A safety barrier, in particular an 'off highway' safety barrier, for protecting the vehicle occupants, pedestrians and other vehicles. The barrier 10 comprises a plurality of first support members 12 for coupling to the ground and providing a predetermined first amount of energy absorption in the event of a vehicle impact; one or more second support members 50 for coupling to the ground and providing a second predetermined amount of energy absorption less than the first amount of energy absorption, in the event of a vehicle impact; and an elongate restraining member 26, e.g. rail, supported by said first and/or second support members at a height above the ground. The first support members may be deflectable; the second support members may be deflectable, yieldable or breakable and may include a weakened or frangible portion with inclusion of a notch or aperture (158, fig.13)</p> |
