Answer: The driver of the brown van And here is why:
A driver changing lanes must yield the right-of-way to any driver already in that lane. However, his problem began much earlier when he didn't notice the sign warning him that the right lane was coming to an end. Good drivers make a habit of looking 10 to 15 seconds ahead of their cars. This way they can spot a problem early, while they still have plenty of time to do something about it. In the city, 10 to 15 seconds is about a block ahead. At highway speeds, it is about a quarter of a mile, or about as far ahead as you can see clearly. 
The driver of the blue minivan might have prevented the accident. He could see that the other driver was not paying attention. He could have dropped back to allow room for a last-minute swerve. |
