If an accident occurs, throw out the bicycle helmet and replace it with a new one. Even if the helmet looks undamaged, it may not be able to withstand the force of another blow.
If you rent a bicycle and helmet for short-term use, examine the helmet closely for signs of damage, such as dents, cracks, scrapes or asymmetry. If a rental helmet looks excessively worn or fits improperly, ask for a different one. |
