Handheld phone use in South Dakota
Handheld phone use while driving is illegal in South Dakota. That covers holding a phone to your ear, dialing by tapping the screen, and resting the phone in your lap to look at it. Hands-free use through a Bluetooth headset, the car's built-in system, or a single voice command is generally allowed for adult drivers.
Texting
Texting while driving is illegal in South Dakota for every driver, regardless of age and regardless of whether the phone is mounted or handheld. The statute covers SMS messages, emails, social-media posts, and reading messages — not just typing them. South Dakota treats texting as a primary offense, meaning an officer can stop you for it without observing any other violation.

Stricter rules for new drivers
In South Dakota, drivers under 18 — and in most cases anyone holding a learner's permit or provisional license — may not use any wireless device while driving, even hands-free. A single citation for a new driver typically extends the supervised period and may push back the date you become eligible for a full license.
School zones and emergencies
Even where hands-free use is otherwise allowed, South Dakota prohibits any phone use in active school zones and construction zones. The exception in every state is true emergencies — calling 911 to report a crash, fire, medical emergency, or crime in progress is always allowed.
What the test asks
Cell-phone questions on the South Dakota permit exam usually present a scenario such as "You are driving with a learner's permit and need to call your parent" — the correct answer is to pull safely off the road first. Memorize the rule that applies to learner-permit holders and you will get those questions right.
