School Zones – What Does “When Children Are Present” Really Mean?”

Q: I always wonder about what “when children are present” on school zone signs means. Does that mean just during school hours or any time you see children? Also does it apply during school hours during the summer vacation (and how are we to know the vacation times?)

A: I thought this would be easy to answer, but it turns out that reading the law about school zone speed limits confuses as much as it clarifies. There’s a good reason many school zones are getting updated with flashing beacons instead of the “when children are present” plaque. But let’s get back to the question.

The Myth of the Above-Average Driver

Instead of starting with a question this week, I’ll start with an answer: Ninety-three percent. Here’s the question: How many American drivers believe they are above average? When drivers were asked to rate their driving ability compared to an average driver ninety-three percent of us thought we were better. You don’t need a statistics class to realize that since only half of any group can be above average, many of us misperceive our driving ability.

Getting High, Getting a DUI, Getting Help

Q: Now that we’ve had a few years of legalized marijuana, do we know what impact that has had on impaired driving?

A: Before I answer that, I’ll point out that understanding traffic data is complex and we can’t always draw accurate conclusions from one set of data. But let’s look at one set of data anyway, because it’s pretty compelling. This chart covers traffic fatalities involving marijuana impaired drivers from 2011 to 2016. That gives us three years prior to legalization and three years since legalization. Continue reading “Getting High, Getting a DUI, Getting Help”

The Trouble With Exit 250

Q: Who has the right of way when exiting northbound from I-5 at Old Fairhaven Parkway; the turning lane trying to get on the on-ramp or the vehicles at the stop sign up the road on the off-ramp?

A: Based on the emails I’ve received about this location, lots of people have opinions about who has the right of way, and they don’t all agree. These emails include stories of angry honking, excessive hand and finger gestures, near-crashes, and a general sense of confusion by people trying to do the right thing, but not knowing for sure what that is.

Different Symbols – Same Meaning

Q: In downtown Bellingham at certain corners of sidewalks there is one of two symbols. The first is a circle in green with a person standing next to a bicycle. The other is a circle in red with a line through the circle showing a person on a bicycle. What do these mean? Does the green one mean that a bicyclist is allowed to ride on the sidewalk, but must get off at the corners? Does the red one mean no bicycling on the sidewalk whatsoever? They are confusing signs since the two seem to be saying two different things; Please explain. Thanks.

A: You’d expect that if you saw two different signs, each of them would have a different meaning. That’s probably where the confusion lies. These two signs each take a different approach to explaining the same law. If we start by examining the law, both the signs should make more sense.

New Distracted Driving Law Now In Effect

As of yesterday, Washington drivers have a new set of rules to follow regarding distracted driving. In the lead-up to the implementation of the law, you may have been bombarded by messages from the state and news stories from your favorite media outlets about the details and consequences of the new law. If you were on a media fast for the last couple months, let me be the first to welcome you to the current era of distracted driving law. This week’s topic might lean a little too far toward the technical side of things, but this new law will affect the current behavior of, based on current data, about 70% of the drivers on the road (you know who you are), so we may as well dig in and understand the new rules.

What Makes a Safe First Car?

Q: My daughter is about to get her driver’s license, and I want to get a vehicle that’ll keep her safe. What do you recommend?

A: Let’s start by agreeing that new drivers are some of the most dangerous people on the road. If we love our kids (of course we do), we want to put them in the safest vehicle possible for their first driving years. It turns out that it’s not easy to choose which car is the safest.
