A testing apparatus and a testing method for a traffic monitoring device with a laser scanner. The testing apparatus has an adjusting plate which provides a receiving place for receiving a traffic monitoring device which is to be tested and a measuring board. A line pattern along an imaginary straight line extending at the height of the reference scanning plane is provided on the measuring board which has a matte black surface. Vertical lines and a diagonal line are arranged on the straight line, and the diagonal line forms an angle with the straight line, which angle is selected in such a way that laser pulses emitted by the laser scanner form at least three laser spots with a reference laser spot width and a reference laser spot length on the diagonal line.
