Ratio of Speed to Stopping Distance

§ 46.2-880. Tables of speed and stopping distances.

All courts shall take notice of the following tables of speed and stopping distances of motor vehicles, which shall not raise a presumption, in actions in which inquiry thereon is pertinent to the issues:

SPEED IN		AVERAGE STOPPING DISTANCES			TOTAL STOPPING DISTANCES
Miles per Hour	Feet per Second	Automobile Brakes (In Feet)	Truck Brakes (Brakes on All Wheels (In Feet)	Average Driver Reaction Time (3/4 seconds) (In Feet)	Automobiles (In Feet)	Trucks (In Feet)
10	14.67	5	7	11	16	18
15	22.0	12	17	16	28	33
20	29.34	21	30	22	43	52
25	36.62	32	47	27	59	74
30	44.0	47	67	33	80	100
35	51.3	63	92	38	101	130
40	58.7	82	120	44	126	164
45	66.0	104	152	50	154	202
50	73.3	128	187	55	183	242
55	80.7	155	227	61	216	288
60	88.0	185	270	66	251	336
65	95.3	217	316	71	288	387
70	102.6	252	367	77	329	444
75	109.9	289	422	82	371	504
80	117.2	328	480	88	416	568
90	132.0	425	607	99	524	706
100	146.6	514	750	109	623	859

The courts shall further take notice that such tables are the result of experiments made with motor vehicles, unloaded except for the driver, equipped with four-wheel brakes, in good condition, on dry, hard, approximately level stretches of highway free from loose material.

Speed Quick Facts

Speeding is one of the most prevalent factors contributing to traffic crashes. The economic cost to society of speeding-related crashes is estimated by NHTSA to be $40.4 billion per year.

In 2007, speeding was a contributing factor in 31 percent of all fatal crashes, and 13,040 lives were lost in speeding-related crashes.

The total economic cost of crashes was estimated at $230.6 billion in 2000. Motor vehicle crashes cost society an estimated $7,300 per second. In 2000, the cost of speeding-related crashes was estimated to be $40.4 billion — $76,865 per minute or $1,281 per second.

Speeding reduces a driver’s ability to steer safely around curves or objects in the roadway, extends the distance necessary to stop a vehicle, and increases the distance a vehicle travels while the driver reacts to a dangerous situation.

For drivers involved in fatal crashes, young males are the most likely to be speeding. The relative proportion of speeding-related crashes to all crashes decreases with increasing driver age. In 2007, 39 percent of male drivers age 15 to 20 who were involved in fatal crashes were speeding at the time of the crash.
