Sponsor: Representative Cook, LD 7
Committee on Transportation & Infrastructure
Overview
Allows the operator of a vehicle or combination of vehicles that are at least 40 feet long or at least
10 feet wide, with due regard for all other traffic, to deviate from their lane when approaching or
driving through a roundabout. Outlines right-of-way requirements in a roundabout and directs the
local jurisdiction or director of the Arizona Department of Transportation (ADOT) to post a sign at
all roundabouts stating that trucks have the right of way.
History
If a roadway is divided into two or more clearly marked lanes for traffic, the following rules apply:
1) A person shall drive a vehicle as nearly as practicable within a single lane and shall not
move the vehicle from that lane until the driver determines they can do so safely. A
motorcycle driver is exempt from this requirement while legally lane filtering;
2) On a roadway that is divided into three lanes, a person shall not drive a vehicle in the
center lane except when overtaking and passing another vehicle if the road is visible and
clear of traffic within a safe distance, or in preparation for a left turn or where the center
lane is reserved for traffic moving in the direction the vehicle is proceeding and is
signposted to give notice of the change; and
3) Official signs may be erected directing slow-moving traffic to use a designated lane or
designating those lanes to be used by traffic moving in a particular direction regardless of
the center of the roadway, drivers of vehicles are required to adhere to the directions of
every sign (A.R.S. § 28-729).
Provisions

2. Asserts that the driver of a vehicle, when approaching or in a roundabout, must yield the right-
of-way to a person driving a vehicle or combination of vehicles that are at least 40 feet long
or at least 10 feet wide feet through a roundabout at the same time or close enough in time to
present an immediate hazard. (Sec.2)
3. Specifies that a person driving through a roundabout is not required to yield to the operator of
a vehicle or combination of vehicles that are at least 40 feet long or at least 10 feet wide who

feet or a width of at least 10 feet approach or drive through a roundabout at the same time or
so close in time as to create a hazard, the driver on the right must yield the right-of-way to the
driver on the left and must slow down or stop if necessary to yield. (Sec.2)
