A coastal city lowered the speed limit on its main highway from 65 miles per hour to 55 miles per hour to improve safety. However, traffic data from the year following the change showed that the total number of serious accidents on that highway actually increased by 10 percent.
Which one of the following, if true, most helps to resolve the apparent discrepancy?
- The lower limit caused heavy congestion, prompting frustrated drivers to make more frequent and risky lane changes.
- A nearby bridge closure pushed a large volume of extra traffic onto the highway soon after the limit was lowered.
- Highway patrol officers issued significantly more speeding tickets after the new limit took effect.
- Most of the accidents that occurred after the change involved only a single vehicle.
- The city posted new signage announcing the lowered speed limit along the entire length of the highway.
