Why should you check clearance for a tall load before departing, not just before reaching a low bridge?

Pick an answer

1. Overhead hazards other than bridges don't affect tall loads
2. There may be other overhead hazards along the route, like wires or awnings, not only official bridge clearances
3. Clearance only ever needs to be checked once, right before the trip begins, something that rarely comes up around bridge
4. Checking clearance only matters on routes with more than one low bridge
