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.
- During the year studied, the highway carried roughly the same total volume of vehicle traffic as it had in the prior year.
- Highway patrol officers issued markedly more speeding tickets to drivers along the corridor once the new limit took effect.
- Most serious accidents that occurred after the change involved only a single vehicle leaving the roadway at low speed.
- The city posted new digital signage announcing the lowered speed limit along the entire length of the busy coastal highway.
