Scooter provided with a steering handlebar and a seat astride which a driver of the scooter may sit, said scooter comprising a windscreen assembly comprising: - a windscreen panel; - a support arm (101; 301) to support the windscreen panel, the support arm (101; 301) comprising a first part (12; 312) of arm configured to be attached to the scooter, and a second part (13; 313) of arm attached to the windscreen panel; wherein said windscreen assembly comprises: - at least one coupling element (14; 324) to rotatably couple the second part (13; 313) of arm to the first part (12; 312) of arm so that the second part (13; 313) of arm is suitable to rotate around a rotation axis from a first angular position to a second angular position in a first direction and from the second angular position toward the first angular position in a second direction opposite the first direction, the first and second angular positions being positions distinct from each other; - at least one blocking element (15; 325) provided to block the second part of arm (13; 313) in the first angular position in a releasable manner; - stop elements (16, 21) operatively positioned between the first and the second part of arm (12, 13; 312, 313) to prevent the second part (13; 313) of arm from rotating in said second direction starting from the first angular position, said stop elements (16, 21) being distinct from said at least one coupling element (14; 324) and distanced from said at least one coupling element (14; 324); characterized in that the windscreen assembly is a windscreen safety assembly and in that the at least one blocking element (15; 325) is suitable to release the second part (13; 313) of arm following the impact of the windscreen safety assembly with a predetermined force of impact so as to allow a rotation of the second part (13; 313) of arm towards the second angular position. - a windscreen panel;
