Why are Texas traffic lights sideways?
Why are Texas traffic lights sideways? What they're saying: Horizontal lights offer better vertical clearance — leading to less chance of damage to the signal infrastructure — and are less likely to be tossed about by gales, Jack Flagler with Austin's Department of Transportation told Axios.
Are traffic lights the same in all countries?
Traffic lights aren't the same all over the planet. Some are to the right of the road. Others hang in the middle of intersections. However, almost all over the world, green means go, yellow means caution (and not “step on the accelerator before the light changes”), and red is a mandatory stop.
