TRUE: Large vehicles have bigger blind spots than regular cars.
Large vehicles (trucks, buses) have significantly larger blind spots on all sides, especially on the left (passenger) side and directly behind the vehicle.
TRUE: When a large truck turns left, its rear wheels track closer to the inside of the turn than the front wheels.
This is called the "inner-wheel difference" (nairinsa).
TRUE: You should never position yourself between a turning large vehicle and the curb.
Due to the inner-wheel difference, large vehicles can trap cyclists, motorcycles, and pedestrians between the vehicle and the curb during turns.
TRUE: If you can see the truck driver in their side mirror, they can also see you.
A general rule: if you can see the truck driver's face in their mirror, they can likely see you.
TRUE: Large trucks need more stopping distance than regular cars at the same speed.
Due to their greater weight, large trucks require significantly more distance to stop than cars.
TRUE: You should always pass a large truck quickly to minimize the time you spend in its blind spot.
When passing a large truck, do it decisively and quickly to minimize time in the truck's blind spot.
TRUE: A large vehicle may swing right before making a left turn to accommodate its turning radius.
Large vehicles often need to swing wide (to the right) before making a left turn.
TRUE: When following a large truck, you should stay far enough back to see the road ahead.
Following too closely behind a large truck blocks your forward vision.
TRUE: Overtaking a large truck creates a wind turbulence effect that can push smaller vehicles.
When passing large trucks at speed, the air displacement creates turbulence that can push or pull smaller vehicles.
TRUE: When a bus signals to pull out from a bus stop, you must yield and allow it to merge.
In Japan, you MUST yield to a bus that is signaling to pull out from a bus stop.
FALSE: Large trucks are not affected by crosswinds as much as smaller vehicles because of their weight.
Large trucks are actually MORE affected by crosswinds because of their large flat sides (high surface area).
FALSE: The speed limit for large trucks on expressways is the same as for regular cars.
Large trucks (over 8 tonnes gross vehicle weight) have a maximum speed of 80 km/h on expressways, compared to 100 km/h for regular cars.
FALSE: You can safely cut in front of a large truck if there is at least one car length of space.
One car length is dangerously insufficient space in front of a large truck.
FALSE: A vehicle displaying a green cross symbol is an emergency vehicle and has priority.
A green cross symbol indicates a pharmacy or medical facility, not an emergency vehicle.
