The present invention provides a road vehicle comprising at least one strengthening member fixed to a structure of the vehicle, preferably extending adjacent to the front windscreen of the vehicle, between lateral edges of the front windscreen, wherein the strengthening member is dimensioned so that it will not prevent the driver seeing an object which is at least two metres from the front windscreen, when the driver uses binocular vision and without requiring the driver to move the driver's head. The present invention may further provide a road vehicle comprising at least one strengthening member which, in a first, storage position is retracted and in a second, extended position, extends between structures of the vehicle, and operating means for moving the strengthening member from the first position to the second position, wherein, if the reinforcing member is for extending adjacent the front windscreen in the extended position, it permits the driver to see through the front windscreen in the second position. A particular type of strengthening member is formed of at least two first linearly extending structural units for extending from the front structure of the vehicle and second linearly extending structural unit joining the at least two first linearly extending units, the second structural units being not horizontal, and wherein the first linearly extending structural units of strengthening member have a width not exceeding 65 mm in the horizontal plane.
