This post will focus specifically on divided highways. Undivided roads often require much lower speeds from the passing vehicles, and in extreme situations, possibly even the need for drivers to stop.
We will discuss the divided highway scenario by talking about a vehicle standing on the shoulder on the right. Naturally, the lateral aspects need to be reversed if the static vehicle is on the left, beside the median.
This unmodified photograph was taken with a long lens from distance, and from two lanes away from the red pick-up truck. The truck driver easily could have changed lanes, away from the man on the shoulder but didn’t. The expression of the man on the shoulder says it all! [Copyright image, 2020]
Remind all the drivers among your family and friends to always look for people doing lane-changes without signalling, particularly at intersections when they realize they’re heading the wrong way! See all five photo’s, below.
