The Shortest Route Isn’t Always The Best Route

Q: Is it legal to walk on the east bound side of the Bakerview I-5 overpass? Also that side has no extra guard rail above the concrete barrier. Isn’t that dangerous for motorcycles and bicycles? Couldn’t they potentially get hit and go flying onto the freeway?

A: Have you ever visited a college campus and seen footpaths through grassy fields created by students who chose the shortest route to their next class, even if that means disregarding the available paved paths?

They are confusing signs since the two seem to be saying two different things; Please explain. Thanks.

A: You’d expect that if you saw two different signs, each of them would have a different meaning. That’s probably where the confusion lies. These two signs each take a different approach to explaining the same law. If we start by examining the law, both the signs should make more sense. Continue reading “Different Symbols – Same Meaning”
