What is the placement requirement for warning signals on all other roadways?

The correct placement requirement for warning signals on all other roadways is to place one signal 100 feet in front of the hazard and one signal 100 feet behind. This spacing ensures that drivers have adequate warning to react to potential hazards, providing enough time to slow down or make an adjustment as needed. The specific distances are designed to account for various speeds and visibility conditions that drivers may encounter on the roadway.

Using a consistent 100-foot distance both in front and behind allows for effective communication of the hazard to other road users within a reasonable range for response. It balances visibility with safety considerations, helping to reduce the risk of accidents in areas where extra caution is needed.
