Hawaii window tint laws require at least 35% VLT on front side windows. The front windshield must allow at least 70% VLT under state law. Rear side and rear windows may be any darkness with dual side mirrors. Coverage includes penalties medical exemption enforcement and the 2025 law update. Rules come from Hawaii Revised Statutes Section 291-21.5 and Act 129.
Key Terms Defined
What VLT Means
VLT means visible light transmission through your vehicle glass and tint. A lower VLT number means a darker window. A higher VLT number means a lighter and clearer window. A 35% VLT window blocks more light than a 70% window. Hawaii sets each window limit using a VLT percentage.
Glazing And Sun Screening
Glazing material means the factory glass installed on your vehicle. A sun screening device means aftermarket film added to that glass. Hawaii law regulates both the glass and the added film. The combined VLT of glass and film must meet each limit. Factory glass must also meet Federal Motor Vehicle Safety Standard 205.
What Hawaii Window Tint Laws Say
Hawaii window tint laws appear in Hawaii Revised Statutes Section 291-21.5. This statute controls sun screening devices on motor vehicles. It bans tint that fails the legal VLT limits. It also bans certain reflective tint colors. You can read it at the Hawaii Revised Statutes Section 291-21.5 page.
The statute sets a VLT limit for each window. It also lists exemptions and prohibited tint finishes. It ties tint checks to the annual safety inspection. It sets fines for owners and installers alike. It requires a compliance certificate for every install.
Front Windshield Tint Rules
The front windshield must allow at least 70% VLT in Hawaii. This keeps the windshield close to plain factory glass. Full windshield film is legal only at 70% VLT or higher. Most aftermarket film falls below that 70% threshold. So full dark windshield tint usually fails the law.
A non reflective strip is allowed at the windshield top. That strip may extend down to the AS1 line. The AS1 line is a factory mark near the top. Without an AS1 mark the strip may reach 4 inches down. This top strip helps cut sun glare for drivers.
Front Side Window Limits
Front side windows must allow at least 35% VLT. This limit covers the driver and front passenger windows. The same 35% rule applies to every vehicle type. The law adds a tolerance of plus or minus 6%. This tolerance accounts for meter and glass differences.
The 6% tolerance sets a practical floor near 29% VLT. Film darker than that floor can fail enforcement. Officers may use a calibrated meter at a traffic stop. A meter reading below the floor can trigger a citation. Staying near 35% gives more margin for inspection.
Rear Window Tint Rules
Rear side windows may be any darkness in Hawaii. The rear window may also be any darkness. This freedom applies across all vehicle types now. Dark rear glass is legal only with dual side mirrors. Both side mirrors must work for this rule.
Sedans gained this rear freedom under the 2025 update. Before that sedans were capped at 35% on rear glass. SUVs and vans and trucks already had darker rear options. A 5% rear tint is now possible with mirrors. A 20% rear tint is also legal with mirrors.
Reflective Colors Are Banned
Hawaii bans mirrored or high reflective tint finishes. This applies to colors seen from outside the vehicle. Banned looks include red or yellow or amber or blue. This color rule covers every window on every vehicle. The ban targets reflective finishes not normal dark film.
Normal dark film without a reflective finish stays legal. The rule focuses on mirror like and metallic looks. A red or amber glare from outside breaks the rule. A blue or yellow mirror finish also breaks the rule. This color ban protects officer visibility into vehicles.
Who The Law Applies To
The tint law applies to all motor vehicles on public highways. It covers sedans and SUVs and vans and trucks. Front window limits are the same for every vehicle type. The 70% windshield rule applies to all vehicles. The 35% front side rule applies to all vehicles.
Federal and state rules both shape Hawaii tint standards. Federal Motor Vehicle Safety Standard 205 governs factory glazing. Hawaii law sets the specific VLT limits and penalties. Hawaii Revised Statutes Section 291C-124 covers driver view obstruction. Both laws can affect items placed on the windshield.
The 2025 Act 129 Update
Act 129 changed Hawaii tint law on May 29 2025. It started as House Bill 226 in the legislature. Governor Josh Green signed the bill into law. This was the largest tint update since 1983. You can review the bill at Act 129 House Bill 226.
The law raised fines for both owners and installers. It added a roll down rule at traffic stops. Drivers with dark rear tint must lower windows for officers. Limited exceptions cover mechanical failure or physical disability. The Department of Transportation must notify inspection stations within 90 days.
Cost Of Legal Tint
Professional tint cost in Hawaii ranges from about $100 to $500. Price depends on film type and vehicle size. Standard dyed film is the most affordable option. Carbon and ceramic films cost more than dyed film. Ceramic film offers stronger heat and UV rejection.
Dyed film often runs $100 to $200 per car. Carbon film often runs $200 to $350 per car. Ceramic film often runs $250 to $500 per car. Legal compliance still depends on VLT not film price. A cheap film can still meet the 35% limit.
Compliance And Inspection Rules
Tint installers must issue a certificate of compliance. This certificate confirms the tint meets Hawaii legal limits. You must keep the certificate inside your vehicle. Officers may request it during a traffic stop. A safety inspector may also ask for the certificate.
A missing certificate counts as prima facie evidence. This evidence points to installer noncompliance under the law. The installer receipt shows who applied the tint. Keep both documents inside the vehicle for proof. Officers may ask for them at any stop.
Tint also factors into the annual safety inspection. A vehicle with illegal tint can fail that inspection. A failed inspection requires removing or replacing the tint. Many shops offer a free reinspection within 30 days. Passing the check keeps your safety tag valid.
Penalties For Illegal Tint
A vehicle owner faces a fine of $300 to $550. Each separate offense can carry its own fine. An installer faces a fine of $700 to $1200. These amounts rose under the 2025 Act 129 update. Older guides may still list lower outdated fine amounts.
An installer must also fix noncompliant tint at no charge. Or the installer must reimburse the owner for new work. The installer receipt can prove who applied the tint. Penalties target both the driver and the installer. Both sides share responsibility for legal tint.
Officers may check tint during any routine traffic stop. A meter reading sets the recorded VLT number. Owners and installers can both face separate fines. The 2025 fine increase raised the maximum installer penalty. That maximum now reaches $1200 per offense.
No Medical Tint Exemption
Hawaii does not allow a medical tint exemption. A doctor note cannot legally permit darker front tint. Front side windows must stay at 35% VLT for everyone. Several exemption bills have failed in the legislature. Act 129 did not add any medical exemption.
Drivers needing sun protection still have legal options. Ceramic film can block most UV rays at legal VLT. This film meets the 35% front side limit. It offers UV protection without an exemption. No statute currently allows darker medical front tint.
Common Tint Misconceptions
Many drivers think sedans still face a 35% rear limit. That cap ended under the 2025 law update. Some believe any windshield tint is fully illegal. A light film at 70% VLT can be legal. A top strip is also allowed near the windshield top.
Some drivers assume a higher number means darker glass. A higher VLT number actually means a lighter window. Others think Hawaii grants medical tint waivers. The state grants no such waiver to anyone. Checking the current statute prevents these common errors.
Verify Current Hawaii Tint Rules
Laws and enforcement may change over time. Check official state sources for the latest tint rules. The Department of Transportation may adopt added enforcement rules. Inspection standards can shift after new agency guidance. Confirm any tint plan against the current statute.
Hawaii window tint laws set VLT limits for each window position. Comparing rules before tinting helps avoid fines. State rules differ widely across the country. Readers comparing states can review our Idaho window tint laws guide. Official Hawaii sources remain the best place to confirm details.
