This year was my turn to take an online Defensive Driving Course to knock a few percent off our automobile insurance premium. It’s admittedly difficult to make traffic law interesting, but this was the worst-written, poorest-edited, and most factually incorrect course I have ever had the misfortune to waste eight hours of my life taking.
For example:
Emergency signals, also called emergency flashers or hazard warning devices, are flashing red lights found on the front and rear of the vehicle
No, they’re amber on both ends of the vehicle. Flashing red on the front is reserved for vehicles with police and firefighters inside.
… material used to block the sun from coming into a vehicle through the windshield and windows must have a luminous transmittance of less than 70%. That means the material must allow at least 30% of the light to pass through it
No, lower transmittance means less light passing through the glass.
I think the author and editors live in a part of the world once colonized by the British Empire:
Here in New York State, we drive on the right.
Update: scruss recalls the image in an old UK driving manual. It describes a type of pedestrian crossing unknown in the US.
The sign recognition lesson claimed this sign marks a section of road with two-lane traffic:
NYS DMV says it actually indicates two-way traffic on an undivided road.
The course says this sign marks the point where the two-lane section ends:
It really means a divided highway ends and two-way traffic begins.
The course definitely offered amusing incorrect answers:
The sign really means slippery when wet, but I suppose that’s in the nature of fine tuning.
The closing page of the course told me I could take a survey, but, somehow, the survey never appeared.
