Happy Birthday to the Zebra Crossing. Introduced on this day in 1951. Remember when riding over one, the white bits are paint and the black bits are Tarmac. The paint gives less grip so always try to ride over the black bits. Also, always look for anyone in walking or running distance of the crossing who may be able to reach it before you. Check your mirrors and be ready to stop if there is anyone nearby. White bits- slippery, Black bits- grippy.
