On The Verge Of A Merge

Q: Recently I was merging onto the freeway, and as I got up to freeway speed on the onramp I found myself next to a car already on the freeway going about the same speed as me. I slowed down to merge behind the car, but that driver slowed down to be kind and let me merge in front. Of course, that doesn’t work well, but it got me wondering who is supposed to do what in that situation.

A: This isn’t the only question about freeway merging that I’ve received. But it’s the nicest. Others blamed poor merging on millennials, political correctness, hostility, and incompetence. I like that you’ve attributed the problem (at least in this case) to kindness.

The Speed Limit on a Freeway Ramp

Q: What is the speed limit on an on- ramp, and when and where does it change? Where I live there is a street that turns into an onramp. This street has a 30 mph speed limit on it. The highway has a 65mph speed limit on it. When and where does that 30 end and the 65 begin?

A: My instinct is to say that onramps are part of the freeway infrastructure and subject to the same speed limits. But once you asked the question I realized that I couldn’t provide you with a law that led me to that conclusion. After searching through state law, the Code of Federal Regulations and the US Department of Transportation’s Freeway Management and Operations Handbook, I still can’t provide a direct quote from the law. That’s not to say it’s not out there, but I haven’t found it yet.

The Slow Merge; It’s More Than a Horsepower Problem

Q: I often see cars enter highways at speeds well below the speed limit. The cars merge without getting up to speed. Other drivers routinely move left to make way for them. I think it’s dangerous for merging drivers to expect those on the highway to yield or slow down. Most often, the cars do reach the speed limit, just later than they should. Maybe those who drive slowly should put on their flasher lights. Wouldn’t it make sense for there to be a minimum speed posted on I-5?

A: Back when America built the interstate system our roads rumbled with V-8 powered cars ready to launch onto any on-ramp and reach freeway speeds before merging onto the highway. At least that’s how I imagine it; the Washington stretch of Interstate 5 was completed in 1969, before I was born. But my imagination doesn’t reflect reality. Yes, the 1970 Cadillac El Dorado had a 500 cubic inch engine (if that doesn’t mean anything to you just know that it’s huge). But as a kid I envied my neighbor’s 1970 Dodge Dart Swinger, a car with about as much power as a Honda Fit. The reality is, as long as we’ve had freeways, there have been cars (and drivers) that don’t reach freeway speeds before merging.

Buses, Merging and Kindness

Q: I know transit buses have a right-of-way when entering traffic from a bus stop. They have a special yield blinker light that they illuminate separate from the left turn signal. I saw a driver use the yield blinker when entering the freeway. Do I have to yield to a bus merging onto the freeway? Legally is the question. I always try to not be a danger/nuisance when large, slow vehicles are trying to deliver children, goods and other things I can’t imagine not having in my life.

A: Just as a matter of survival, it’s always wise to yield to buses. Maybe it’s not always the law, but it is the rule of lug nuts. If you’re not familiar with that rule, it states that in any given collision between two vehicles, the one with the most lug nuts wins. Using the word “wins” in the context of collisions is admittedly crude, but you get my point. For anyone concerned with their own well-being, the rule of lug nuts should be enough. I appreciate that you went beyond that and also have concern for the people (and goods) onboard big vehicles.

Learning to Merge

Q: How are drivers supposed to merge onto the freeway? It seems like most drivers in Bellingham expect to merge into traffic immediately when they enter the on-ramp instead of getting up to speed and “zipper-merging” near the end of the on-ramp lane. Entering drivers seem to think its their right to merge into traffic before getting up to speed and expect other drivers to slow down or change lanes to make room for them, creating hazardous conditions for all drivers in their area. What is the law?

A: With increased summer-time traffic, along with more freeway lane closures as road crews maximize the good weather, summer is the season of merging frustration. Although, as traffic has increased in the Northwest, any day can include merge-induced headaches. We might be able to alleviate some of those headaches if we could all agree on the best way to merge. Whether it’s merging onto the freeway from an on-ramp, as this question poses, or merging due to a lane closure, research shows that there really is a best way. Continue reading “Learning to Merge”
