Laws regarding when drivers must yield the right of way to pedestrians vary from state to state and are usually located in a state’s statutes—often in the motor vehicle code, traffic code, or transportation code, for example. Cities and towns (municipalities) may also have local laws (ordinances) that govern when and where pedestrians or drivers have the right of way.

Although laws vary from state to state, in most states:

• Drivers must yield the right of way to pedestrians at marked and unmarked crosswalks.

• Drivers must yield to a pedestrian crossing on a sidewalk in front of an alley, building, driveway, or private road.

• Drivers must yield to a pedestrian crossing the street and approaching the driver’s half of the roadway.

And in most states:

• Pedestrians must yield the right of way to motor vehicles if the pedestrian is crossing anywhere other than a marked or unmarked crosswalk.

• When there are traffic lights present, pedestrians may only cross when there is a flashing walk signal (often showing the seconds remaining in the walk period).

In Missouri, the laws regarding the right of way for pedestrians are outlined in the state's Revised Statutes, specifically within the rules of the road. Drivers in Missouri are required to yield the right of way to pedestrians at both marked and unmarked crosswalks. Additionally, when a pedestrian is crossing a sidewalk that extends across an alley, driveway, or building entrance, drivers must yield to them. If a pedestrian is already crossing the road and is on the same half of the roadway as the driver or is approaching so closely from the opposite half to be in danger, drivers are also required to yield. Conversely, pedestrians must yield the right of way to vehicles when crossing the road at any point that is not a marked or unmarked crosswalk. In situations where traffic control signals are in place, pedestrians are obliged to follow the signals and may only cross during the designated walking period indicated by a walk signal. Local municipalities may have additional ordinances that further dictate the specifics of right-of-way laws, so it is important for both drivers and pedestrians to be aware of and comply with both state statutes and local ordinances.
