Daniel Sheflin, a retired technology executive, emphasizes the importance of hand signals for cyclists in his document. He describes the basic hand signals used for left turns, right turns, and stopping, detailing the correct arm positions for each signal. These signals are crucial for ensuring safety while cycling on both busy streets and off-road trails.

Important Cycling Hand Signals

2. Introduction
 After a successful career in the technology and
engineering industries, Daniel Sheflin retired in 2015
as vice president of technology automation control
solutions at Honeywell in Golden Valley, Minnesota.
Now, Daniel Sheflin enjoys staying active through
cycling and fat biking.
Whether riding alongside automobiles on a busy city
street or taking a mountain bike off the road, cyclists
must use proper hand signals at all times. Three basic
signals are used to alert fellow riders and other
vehicles to an upcoming left turn, right turn, or stop.
To indicate a left turn, riders simply raise their left arm
perpendicular to the road. It can be helpful to keep
one’s fingers flat and pointed in the direction of the
turn.

3. Cycling Hand Signals
 A right turn signal is made in the same fashion,
but with the right arm rather than the left.
However, cyclists more commonly use their left
arm to signal a right turn. To do so, riders should
first make the left turn signal. From there, riders
can bend the arm at the elbow and make a right
angle, so that the fingers point straight up. Finally,
to signal a stop, riders should follow the right turn
signal instructions. However, instead of pointing
up, riders should bend their arm so that the hand
points down toward the road.
