Discription of Events: On 9/13/18 an elderly driver in front of me drove below the speed limit on Route 35 from Wall Township into Sea Girt. He continued to straddle the shoulder for about 1 mile only moving into the proper lane when he approached a truck that was parked on the shoulder. Then he went back to straddling the shoulder. He applied his brakes abruptly at a yellow light at the intersection of Sea Girt Ave. He then proceeded through the intersection and eventually made a left into the Sea Girt Foodtown parking lot.
