Today I was stopped with my 45 E-Retro-Roller, I think because I hit the traffic light too fast as the patrol car was behind me. They called it traffic control. Although I screwed on my new sheet metal plate and had the insurance card with me still to send the copy of the insurance certificate, although vehicle ID and card agree? I should probably have another sign on the E-Retro-Roller, like on the e-scooter with hologram. Gi bt there really regulations there? Until then always had the plates without hologram on the e-retro-roller. I thought I actually had to get one with hologram issued. So always on all 45-50 ccm rollers (Vespa, Simon, E-retro-roller) the normal sheet metal sign and only on the 20 kmh e-scooter such a glue sign with hologram. With the insurance you can not reach any. 44 minutes waiting time in the loop… ?? wanted to ask there again. I ask you one more time. to get the wrong sign from the insurance company?
