99 year old on wrong side of road and no headlights in RV

We recently had ne road construction (new asphalt) on state route 4 lanes and at every intersecting roadway in the opposing travel lanes are big arrows pointing direction of travel ex... southbound lanes have big arrows painted pointed south as you cross to go into northbound lanes arrows are pointed north at all intersections not sure if it has helped but it adds to the one way directional signs and do not enter signs posted. I knew a old timer who didn't like our town's DMV as they wouldn't pass him so he would go away 30 miles to a smaller town and use their DMV and would pass every two years. Never understood how but he passed away and we and his family were relieved.
