Caution Sign: Speed Bumps Ahead

Caution Sign: Speed Bumps Ahead — High-Visibility 3M Engineer Grade Reflective Aluminum

The Speed Bumps Ahead caution sign (Part# LS-11508) is a professionally manufactured traffic warning sign designed for contractors, facility managers, and site safety coordinators. Constructed from 63 mil thick aluminum with 3M Engineer Grade reflective sheeting, it delivers reliable daytime and nighttime visibility in parking lots, job sites, and roadway applications. The laminated finish and pre-punched mounting holes make installation straightforward and ensure long-term durability in outdoor environments.

Technical Specifications

Unlike standard painted or non-reflective signs, this sign uses 3M Engineer Grade reflective sheeting laminated onto heavy-gauge aluminum, providing a significant upgrade in nighttime conspicuity and weather resistance. Contractors who require higher visibility performance can also select the 3M Hi Intensity or 3M Diamond Grade reflective aluminum variants for more demanding applications.

Key Features & Benefits

63 Mil Thick Aluminum Construction

The heavy-gauge aluminum substrate resists bending, warping, and impact damage common on active job sites. This thickness ensures the sign maintains its shape and legibility throughout extended outdoor use.

3M Engineer Grade Reflective Sheeting

3M Engineer Grade reflectivity provides reliable retroreflective performance, making the sign clearly visible to drivers and equipment operators in low-light and nighttime conditions. This is a recognized standard for traffic and safety signage.

Laminated Finish for Superior Durability

The laminated surface protects the sign face from UV fading, moisture, and abrasion, extending service life in harsh outdoor environments. Contractors benefit from reduced replacement frequency and lower long-term costs.

Pre-Punched Holes and Rounded Corners

Factory-installed mounting holes and rounded corners allow for fast, tool-ready installation on posts, fences, or structures without additional fabrication. Rounded corners also reduce snag and injury hazards during handling and installation.

Multiple Reflective Material Options

Available in 3M Engineer Grade, Hi Intensity, and Diamond Grade reflective aluminum, allowing contractors to match the sign specification to the visibility requirements and budget of each specific project.

Common Applications

Parking Lot Safety

Alerts drivers to speed bumps in commercial and institutional parking facilities, reducing vehicle damage and pedestrian injury risk.

Construction Site Traffic Control

Used on active job sites where temporary speed control measures such as speed bumps have been installed to manage vehicle and equipment traffic.

Private Road and Campus Environments

Suitable for industrial campuses, warehouses, and private roads where speed bump warning signage is required for safety compliance.

Nighttime and Low-Light Environments

The 3M Engineer Grade reflective sheeting ensures the sign remains visible to drivers in low-light conditions, making it appropriate for locations without adequate ambient lighting.

Compatible Materials

• Standard sign posts (round and square)
• Chain-link fencing (with appropriate hardware)
• Wood posts and structures
• Wall and barrier mounting surfaces
