It could be general anxiety but does anyone else get uncomfortable when you're either behind a tanker or next to one? Maybe the irrational discomfort I feel when near these types of semis has to with playing too much Grand Theft Auto. All the tankers in those games explode like a massive fireworks display.

I was behind one of these bad boys (or bad girls?) on Bypass 20 over the weekend and noticed the tanker in front of me had the usual triangle-shaped placard and a number on it. I told Siri to remind me to look up what it was when I reached my destination.

There are way too many number codes so I won't bore you and drag this article on and on and on. Instead, the color explanations will be a great deal of help if you too are inquisitive.

THE COLORS AND THEIR MEANING

Orange is all sorts of bad. Bad, bad, bad, bad. A tanker with an orange placard on the back means explosive materials like dynamite, fireworks, and ammunition are being transported. Just like the tankers in GTA.

Red isn't favorable either. This means flammable goods like gasoline, rubbing alcohol, paint, and acetone are on board. Sure, they won't explode per se but I don't want to near them while traveling at high speeds.

Green labels aren't a big deal but white could cause biohazardous or toxic materials.

Yellow and blue are usually combustible as well.

The placards with multiple colors vary from combustible, explosive, hazardous to the environment, bad news for your skin or lungs, or worse.

LOOK: See how much gasoline cost the year you started driving

To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Using data from the Bureau of Labor Statistics (released in April 2020), we analyzed the average price for a gallon of unleaded regular gasoline from 1976 to 2020 along with the Consumer Price Index (CPI) for unleaded regular gasoline from 1937 to 1976, including the absolute and inflation-adjusted prices for each year.

Read on to explore the cost of gas over time and rediscover just how much a gallon was when you first started driving.
