🔍 Key Concepts

• Standard crane hand signals used in marine and industrial operations • How "slow" is usually indicated in addition to a normal motion signal • Differences between starting a motion, changing speed, and emergency stop signals

💭 Think About

• Look for the option that describes a modification to an already normal motion signal to indicate a slower speed, rather than a completely different motion. • Ask yourself which answer sounds like a small change to any existing direction signal (up, down, hoist, lower, swing) that can be added to it to mean "slow". • Consider which choices look more like special-purpose signals for something else (like starting a series of signals or signaling an emergency) rather than just slowing a movement.

✅ Before You Answer

• Identify which choice clearly shows two hands being used with one hand modifying the other to change the meaning to "slow". • Make sure the signal described can logically be used with any motion signal (up, down, swing, travel). • Eliminate any option that sounds like it would be confused with a start, stop, or emergency signal rather than "slow".
