On the NCEES exam outline, for the Transportation exam specs (both AM and PM actually), it lists:
"Vertical and/or horizontal clearances".
It's clear to me what vertical clearances are (a vertical curve clearing a pipe below or a bridge above, etc.) but what do you think is meant by horizontal clearances?

Thanks.
