Plain-English summary for informational purposes only—not legal advice. Laws change; verify specifics on official Arizona sources (e.g., A.R.S.).

Pre‑trip walk‑through (AZ)
Brake controller connected; gain set; test at 20–25 mph
Lights: running, brake, turn; license plate illuminated
Breakaway battery charged; cable clipped to vehicle frame
Safety chains crossed under tongue; coupler latched and pinned
Tire PSI set (truck + trailer) and lug nuts torqued
Mirrors adjusted; load secured; straps tagged/rated
After 5–10 miles: quick check
Strap tension even; no chafing; edge protectors in place
Hubs warm (not hot); tires wearing evenly; no wobble
Basics to keep in mind
·Brakes & lights: Make sure your trailer brakes and lights work. A proportional brake controller is strongly recommended for stability and stopping distance.
·Safety chains & breakaway: Cross chains under the tongue and clip the breakaway cable to the tow vehicle—not the chain.
·Secure load: Use rated straps/anchors; recheck after the first 5–10 miles and each fuel stop.
·Speed & spacing: Leave extra room; Arizona winds and heat increase stopping distances.
·Wide turns & fuel stops: Make WIDE turns to avoid the trailer running into/over something or driving up on a curb or sidewalk. Severe tire, axle, trailer body and property damage may occur—especially leaving gas stations. Do a quick map check of your intended stations so you know the best pull‑in and pull‑out path.
Good-neighbour East Valley tips
·Avoid lingering in the left lane when towing.
·Lane discipline: A.R.S. §28‑721 directs drivers to keep right except when passing, with exceptions for closures, one‑way roads, or multi‑lane divisions.
·Give semi trucks and buses extra space—they create strong bow waves.
·Mind driveways and dips to avoid dragging long trailers.
Pro tip
·Do a quick walk‑around after hitting freeway speeds the first time. Heat and vibration can loosen fresh straps.
