All states have laws that prohibit drivers from making an illegal or improper turn. Common examples of illegal or improper turns are:

• U-turns (when there is a No U-Turn sign)

• Making a right or left turn without first moving to the far right or left lane

• Making a right or left turn when there is a sign at the intersection that prohibits such turns (No Right Turn).

The penalty for making an illegal or improper turn usually includes a fine and points on your driver’s license.

As with many traffic violations, the officer issuing the citation and the prosecutor have significant discretion in determining whether there was a violation of a traffic law and whether the violation constitutes a certain offense, as defined by the state legislature in the traffic code or in a municipal ordinance.

This discretion to issue a ticket or citation and prosecute the charge against the driver is balanced by the discretion of the jury or judge in determining whether the prosecution met its burden of proof sufficient to convict the driver (for a criminal offense) or find the driver responsible (for a civil infraction, violation, or offense).

In Utah, as in all states, there are specific laws that govern the legality of turns made by drivers. Illegal or improper turns include executing a U-turn where it is prohibited by signage, turning without moving to the appropriate lane (far right for right turns, far left for left turns), and making turns where signs indicate they are not allowed. The penalties for such violations typically involve a monetary fine and the addition of points to the driver's license, which can affect insurance rates and driving privileges. Utah law enforcement officers have the discretion to issue citations for these violations, and prosecutors decide how to charge the offense. However, the final determination of guilt or responsibility lies with a judge or jury, who must be convinced by the prosecution that the driver committed the offense beyond a reasonable doubt in criminal cases, or by a preponderance of the evidence in civil infractions.
