From our Commercial Drivers Manual:
When Passing. Whenever you are about to pass a
vehicle, pedestrian, or bicyclist, assume they don’t
see you. They could suddenly move in front of you.
When it is legal, tap the horn lightly or, at night,
flash your lights from low to high beam and back.
And, drive carefully enough to avoid a crash even if
they don’t see or hear you.
Contradicting the Drivers’ Manual:
As you approach a bicyclist, slow down. Avoid
honking your horn. Bicyclists can usually hear an
approaching vehicle and loud noises can startle
bicyclists, causing a crash .
And contradicting state law § 22-223.(c) that prohibits use of high beams within 300 feet of ANY vehicle including a bicycle.
I really wish they put in something about being extra careful for bike/peds when turning as a turning truck killed Jack Yates, Alice Swanson … FARS shows trucks kill more bicyclists then passenger cars and trucks use the right side of their vehicle to kill more frequently then cars as well.
To show how bad a blind spot is for trucks this UK video shows just how many bicyclists can be hidden in a trucks blind spot.
