Parking and traffic-control signs

Private-property parking signs commonly use 12 × 18-inch aluminum layouts. Public-road applications can be governed by the current MUTCD plus state and local adoption rules.

• Confirm whether the sign controls a private lot or public roadway.
• Choose reflective material where nighttime visibility matters.
• Verify arrows, mounting orientation and the exact restriction wording.
• Use local towing language where required rather than assuming one layout works everywhere.

Accessible parking

Federal ADA standards require the International Symbol of Accessibility on identification signs and “van accessible” wording for van spaces. State and local rules can add design, fine, towing or mounting requirements.

• Confirm the number and type of spaces required.
• Check state-specific sign wording before purchase.
• Coordinate the main sign with any van-accessible or fine placard.
• Confirm mounting height and location as part of installation.

Property and security notices

No-trespassing, private-property and surveillance signs have broad everyday demand, but legal-notice requirements vary by jurisdiction and intended enforcement.

• Use wording that matches the property policy and local rule.
• Make the sign visible at entrances and likely access points.
• Choose aluminum for long-term exterior exposure.
• Do not assume a surveillance notice creates or replaces a security system.

Facility and life-safety signs

Exit, fire-extinguisher and hazard signs can support a safety program, but a small catalog marker may not replace illuminated, tactile, photoluminescent or code-specific equipment.

• Identify the authority having jurisdiction for the building.
• Confirm whether the product is supplemental or code-required.
• Check illumination, visibility, mounting and language requirements.
• Keep required signs unobstructed and maintained.

Material and durability

The cheapest substrate is rarely the cheapest lifecycle choice. Match material to exposure, mounting and replacement expectations.
