Commercial trucks have massive blind spots—areas where truck drivers cannot see other vehicles, motorcycles, or pedestrians. These “no-zones” extend far beyond what most Phoenix drivers realize, creating deadly hazards on I-10, Loop 101, and throughout the Valley. When truck drivers fail to properly check these blind spots before changing lanes or turning, catastrophic accidents result.

Understanding Truck Blind Spots (No-Zones)

Unlike passenger vehicles with relatively small blind spots, commercial trucks have enormous areas where the driver’s view is completely obstructed:

Front Blind Spot

• Extends 20 feet or more: Directly in front of the cab
• Why it exists: High seating position blocks view of road immediately ahead
• Danger: Truck driver can’t see vehicles that cut in front too closely
• Common accidents: Rear-ending stopped vehicles, hitting pedestrians in crosswalks

Rear Blind Spot

• Extends 30 feet or more: Entire area directly behind trailer
• Why it exists: No rear-view mirror, trailer blocks all rear vision
• Danger: Driver cannot see vehicles following too closely
• Common accidents: Backing accidents, sudden stops causing rear-end collisions

Right-Side Blind Spot

• Extends entire length of truck: From cab to end of trailer
• Extends 2-3 lanes wide: Covers multiple traffic lanes
• Why it exists: Driver sits on left side, right side is far from driver’s position
• Most dangerous blind spot: Largest no-zone area
• Common accidents: Right-turn squeeze, lane change collisions

Left-Side Blind Spot

• Extends from cab to mid-trailer: Smaller than right side but still significant
• Extends 1-2 lanes wide: Covers adjacent lane
• Why it exists: Mirrors don’t cover entire left side
• Common accidents: Lane change collisions, merging accidents

Common Blind Spot Accidents in Phoenix

Lane Change Collisions

Truck driver changes lanes without seeing vehicle in blind spot:

• Passenger vehicle sideswiped or crushed
• Particularly common on I-10 and Loop 101
• Often occurs when truck moves right to exit
• Motorcycles and small cars especially vulnerable

Right-Turn Squeeze Accidents

Truck makes wide right turn, crushing vehicle in right blind spot:

• Truck swings left before turning right
• Vehicle pulls alongside on right during turn
• Trailer sweeps across and strikes vehicle
• Common at Phoenix intersections with tight corners
• Pedestrians and cyclists also at risk

Merging Accidents

Truck merges onto highway without seeing vehicle in blind spot:

• Truck entering I-10 or Loop 101 from on-ramp
• Vehicle in adjacent lane gets sideswiped
• Forced off road or into other traffic
• High-speed impacts cause severe injuries

Backing Accidents

Truck backs up without seeing vehicle or pedestrian behind:

• Delivery trucks in parking lots
• Trucks backing into loading docks
• Vehicles or pedestrians crushed
• Often occur at warehouses and distribution centers

Passing Accidents

Vehicle attempts to pass truck in blind spot:

• Truck begins lane change while vehicle is passing
• Vehicle trapped between truck and barrier
• Forced off roadway
• Particularly dangerous on highways

Truck Driver Duties Regarding Blind Spots

Federal Regulations

Commercial truck drivers must comply with Federal Motor Carrier Safety Regulations:

Mirror Requirements (49 CFR § 393.80)

• Two rear-view mirrors (one on each side)
• Mirrors must provide view along sides of vehicle
• Must be properly adjusted
• Must be maintained in working condition

Driver Training Requirements

• Training on blind spot awareness
• Proper mirror adjustment and use
• Safe lane change procedures
• Backing safety protocols

Standard of Care

Truck drivers must exercise reasonable care, including:

• Check mirrors repeatedly: Before and during maneuvers
• Signal intentions early: Give other drivers warning
• Make multiple checks: Look multiple times before changing lanes
• Avoid sudden movements: Gradual lane changes allow others to react
• Use spotters when backing: Have someone guide backing maneuvers
• Maintain mirrors: Keep mirrors clean and properly adjusted

Technology Solutions

Modern safety technology can reduce blind spot accidents:

• Blind spot monitoring systems: Sensors detect vehicles in no-zones
• Side-view cameras: Provide additional visibility
• Collision warning systems: Alert drivers to potential impacts
• Convex mirrors: Wider field of view

Important: Trucking companies that fail to equip trucks with available safety technology may be liable for negligence.

Determining Liability in Blind Spot Accidents

Truck Driver Negligence

Drivers are liable when they:

• Fail to check blind spots before maneuvering
• Don’t use turn signals
• Make sudden, unsafe lane changes
• Ignore blind spot warning systems
• Have improperly adjusted mirrors
• Drive while distracted or fatigued

Trucking Company Negligence

Companies may be liable for:

• Inadequate training: Not properly training drivers on blind spot awareness
• Negligent hiring: Employing drivers with poor safety records
• Failure to equip safety technology: Not installing available blind spot systems
• Poor maintenance: Broken or misaligned mirrors
• Unrealistic schedules: Pressuring drivers to rush

Comparative Negligence

Other drivers may share fault if they:

• Lingered in truck’s blind spot unnecessarily
• Passed on the right side
• Cut in front of truck too closely
• Failed to maintain safe following distance

However, even if you were in a blind spot, the truck driver still has a duty to check before maneuvering. Arizona’s comparative negligence law allows recovery even if partially at fault.

Evidence in Blind Spot Accident Cases

Electronic Data

• Black box data: Speed, braking, steering inputs
• Electronic logging devices: Driver hours and fatigue
• GPS data: Truck’s exact position and movements
• Blind spot system data: Whether warnings were activated

Physical Evidence

• Vehicle damage patterns showing point of impact
• Skid marks and debris
• Mirror condition and adjustment
• Dash cam or truck camera footage

Witness Testimony

• Other drivers who saw the accident
• Testimony about truck’s movements
• Whether turn signals were used
• How long vehicle was in blind spot

Expert Analysis

• Accident reconstruction: Determine how crash occurred
• Trucking industry experts: Testify about proper procedures
• Visibility studies: Show what driver could or couldn’t see

Preventing Blind Spot Accidents

For Passenger Vehicle Drivers

• Stay out of no-zones: If you can’t see truck’s mirrors, driver can’t see you
• Pass quickly and safely: Don’t linger alongside trucks
• Never pass on right: Largest blind spot is on right side
• Leave space when cutting in: Allow several car lengths before moving in front
• Be patient: Give trucks room to maneuver
• Watch for turn signals: Trucks need extra room to turn
• Avoid following too closely: Stay out of rear blind spot

For Truck Drivers

• Check mirrors constantly
• Signal lane changes well in advance
• Make gradual lane changes
• Use spotters when backing
• Keep mirrors clean and adjusted
• Use blind spot monitoring systems
• Take extra time at intersections

Compensation for Blind Spot Accident Injuries

Common Injuries

• Traumatic brain injuries: Head impacts, concussions
• Spinal cord injuries: Paralysis, nerve damage
• Crush injuries: When vehicle is compressed
• Broken bones: Fractures throughout body
• Internal injuries: Organ damage, internal bleeding
• Wrongful death: Fatal injuries from high-impact collisions

Available Damages

• Medical expenses: Emergency care, surgery, hospitalization, rehabilitation
• Future medical costs: Ongoing treatment, assistive devices
• Lost wages: Income lost during recovery
• Lost earning capacity: Permanent disability affecting work
• Pain and suffering: Physical and emotional distress
• Property damage: Vehicle total loss
• Wrongful death damages: Loss of support, companionship, funeral expenses

Frequently Asked Questions

What if I was passing the truck when it changed lanes?

The truck driver still has a duty to check blind spots before changing lanes. Even if you were passing, the driver should have seen you in mirrors or used blind spot monitoring systems. You may recover substantial compensation even if you were in the blind spot, though your recovery might be reduced if you were passing on the right or lingering unnecessarily.

Can I sue if the truck had blind spot monitoring but the driver ignored it?

Yes. Having safety technology doesn’t help if the driver ignores warnings. In fact, this may strengthen your case by showing the driver had clear notice of your presence but failed to act. This could support claims for punitive damages.

What if the trucking company claims their driver couldn’t see me?

That’s exactly the point—truck drivers must account for blind spots by checking multiple times, signaling early, and making gradual movements. Saying “I couldn’t see them” is an admission of negligence, not a defense. Drivers are responsible for knowing their blind spots and compensating for them.

How do I prove the truck driver didn’t check their blind spot?

Evidence includes witness testimony, video footage, the driver’s own statements, and expert analysis of the accident. If the driver changed lanes suddenly without signaling or made an unsafe maneuver, this suggests failure to properly check blind spots. Your attorney can subpoena truck data and company records to build your case.

What if I was on a motorcycle when hit by a truck changing lanes?

Motorcycles are especially vulnerable in truck blind spots due to their small size. However, truck drivers have an even greater duty to watch for motorcycles. Arizona law requires drivers to exercise extra caution around motorcycles. You have strong grounds for a claim if a truck driver failed to see your motorcycle before changing lanes.

Can I recover compensation if the accident happened on I-10 during rush hour?

Yes. Heavy traffic doesn’t excuse negligent driving. In fact, truck drivers must exercise even greater caution in congested conditions. Rush hour on I-10 is predictable, and drivers must adjust their behavior accordingly. The trucking company cannot use traffic as an excuse for their driver’s failure to check blind spots.
