In this photo made Wednesday, Nov. 1, 2017, a driver stays in the passing lane as traffic accumulates behind along I-70 in Montgomery County, Mo. Many states have laws against driving in the left lane except for passing or turning left, which are often ignored by drivers, leading to annoying and dangerous bottlenecks that some experts say are as bad as driving too fast because people get trapped behind and become frustrated prompting some to drive more aggressively.
