Ch. 2 · Pedestrian Conduct

Which of the following is an incorrect standard for the emergency stop device of a remotely operated small vehicle?

[Multiple choice · Hard]

• A.The push button must be limited to one that can be easily operated from the front and rear of the vehicle body
• B.The push button must be easily identifiable due to a large difference in brightness or other factors between the push button and the surrounding area
• C.It must immediately stop the motor when activated
• D.The push button must be limited to one that can be easily operated from the side of the vehicle body✓

Momoka

Hmm, having the button on the side sounds pretty convenient for an emergency, doesn't it?

Hikari

That's the trap — the rules say the button must be operable from the front and rear, not the side. So option 4 is the incorrect one.

Momoka

Oh, so they want you to reach it while walking behind or in front of the vehicle?

Hikari

Exactly. Front and rear access makes sense for someone following or facing a remotely operated vehicle.
