Perhaps you think you can characterize Washington drivers pretty accurately. After all, you've observed how often they signal, how closely they follow other cars, how fast they go down Interstate 5, and you've heard how often they lay on the horn.
But I bet you two traffic tickets and a gallon of gas that you don't know everything. A look back at this year in traffic data reveals some interesting tidbits about attitudes, behaviors and trends among Washington drivers.
What percentage of people wear seat belts in Washington?
Washington boasts the highest seat belt usage rate of any state -- 97.5 percent, according to the National Highway Traffic Safety Administration. Oregon is not far behind at 96.6 percent. The national average is 84 percent.
Curious which state you'll find the most unbuckled occupants? It's Massachusetts, with a 77.3 percent usage rate. This rate is an improvement, though; in 2004, 63.3 percent of people in the Bay State wore seat belts.
What percentage of people wear seat belts in Clark County?
A whopping 99.1 percent. We're bringing up the state average! In 1986 the local seat belt usage rate was 39.9 percent.
What stretch of 60 mph freeway in Vancouver has consistently made the state's top 10 list for speeding?
Interstate 205 southbound at Mill Plain Boulevard. In the last quarter of 2011, it reported the highest average speed for a 60 mph zone: 65.3 mph, according to the Washington State Department of Transportation. This area's ranking dropped to ninth in the first quarter of 2012, back up to eighth in the second quarter and then was sixth-fastest in the third quarter.
Speeding is common on interstate freeways across the state, with more than half of all drivers observed going over the posted speed limit.
Speaking of speeding -- what percentage of Washington drivers think they're likely to get a ticket for going 68 mph in a 60 mph zone?
In a 2012 survey conducted by the Washington Traffic Safety Commission, 78 percent of respondents said they would be very likely or somewhat likely to get a ticket for going eight miles over the speed limit. Trooper Will Finn, spokesman for the Washington State Patrol, says troopers take multiple factors into account when deciding whether to pull someone over for speeding. They consider how heavy traffic is, what the weather conditions are and if the driver is following too closely or driving aggressively.
So, what if a driver hits all those factors during the busy winter holiday travel season?
"Absolutely, we're going to stop him," Finn said.
It's up to the discretion of the trooper to decide whether to ticket the driver.
Through which two media outlets do Washington drivers most commonly learn about speed enforcement?
Among the surveyed drivers, 47.1 percent said television was the most common way they heard or saw a campaign about speed enforcement while 40.8 percent said radio. Interestingly, most young adults (ages 18 to 24) get their info on speed enforcement from electronic signs. It's also the most popular means in the Vancouver area.
Did the state's traffic fatality rate increase or decrease from 2010 to 2011?
OK, that was a trick question. It stayed the same; in 2010 the fatality rate dipped to 0.80 per 100 million vehicle miles traveled, the lowest rate in state history, and stayed there.

Impaired driving. According to the Washington Traffic Safety Commission's 2012 report, 50.9 percent of fatal accidents involve drivers under the influence of alcohol or drugs. A lot of fatal accidents also involved young drivers (42.6 percent) or speeding (40.7 percent).

What factor is involved in half of all fatal traffic accidents in Vancouver?
Speeding. Distracted driving is another factor involved in a lot of fatal accidents -- 42.9 percent of them to be exact. Impaired driving and young driver-involved fatals aren't far behind, each getting 39.3 percent.
