Right turn hand signal. To signal your intention to turn right, rest your left elbow on the windowsill and raise your forearm up so it forms a 90-degree angle with your arm. Keep your left hand open. To make a left-turn hand signal, act as if youâre physically blocking someone with your arm.

Ensure you are in the left-turn lane, then push the turn signal lever down gently with your left hand. When the turn signal locks in place, youâll be able to see a flashing arrow directed to the left on your instrument cluster. Youâll also hear a tick-tock sound which clicks in time with the flashing of the light.
