The roadway shock-absorber according to the present invention absorbs shocks applied by a crashing vehicle, or reduces the speed of the vehicle and simultaneously prevents it from leaving the lane and crashing into oncoming traffic in the opposite direction, thus enabling the vehicle to return to its normal advancing direction. |
