WebMay 12, 2024 · A minimum speed limit is often posted on interstates, expressways, and freeways. Advisory speed signs have black letters on a yellow background. Advisory speed signs are often seen under a warning sign and are typically placed at sharp curves, exits, or exit ramps. What You Should Know about the Advisory Speed Sign WebThe relationship between curve design and driver speed choice is described in Section 2.2.1, and the relationship between curve design and crash rate is explored in Section 2.2.2.. 2.2.1 Curve Speed. A review of the literature indicates that several variables can have an influence on curve speed. These variables include: Radius, Superelevation
