Be particularly careful around trucks. The drivers have reduced range of vision. If you hear a large vehicle behind (you can usually hear a large truck), be particularly cautious and even stop and get off the road — especially if you are in a more industrial zone. Wait for the vehicle to pass. Too many cyclists have been killed by large vehicles (the city’s Department of Transportation estimates that they are responsible for more than half of cycling deaths in 2019). They shouldn’t be permitted to drive around the city at high speeds with impunity, but until education and enforcement address this, extra caution is required.
