Minimum Spacing between Vehicles during Overtaking Calculator

Minimum Spacing Formula:

\[ s = (0.7 \times V_b + 6) \]

Minimum Spacing (m):

With ±5% Tolerance (m):

Definition: This is the minimum distance required between two vehicles when one is overtaking the other to ensure safe maneuver.

Purpose: It helps drivers maintain safe distances during overtaking to prevent accidents.

The calculator uses the formula:

\[ s = (0.7 \times V_b + 6) \]

Where:

Explanation: The formula accounts for reaction time and braking distance needed for safe overtaking.

Details: Proper spacing ensures safe overtaking maneuvers, prevents collisions, and accounts for reaction times.

Tips: Enter the speed of the slow-moving vehicle in m/s and tolerance percentage (default 5%). All values must be ≥ 0.

Q1: Why is the formula 0.7*Vb + 6?
A: The 0.7 factor accounts for reaction time and the +6 provides a minimum safety buffer distance.

Q2: What's a typical tolerance percentage?
A: ±5% is commonly used to account for variations in vehicle performance and road conditions.

Q3: When would I change the tolerance?
A: Increase tolerance in poor weather conditions or with heavier vehicles.

Q4: How do I convert km/h to m/s?
A: Divide km/h by 3.6 (e.g., 50 km/h = 13.89 m/s).

Q5: Does this include safety margins?
A: The basic formula includes some safety margin, but the tolerance adds additional safety buffer.
