The speed bump is an increased hazard to the unwary, a challenge to the daredevil, a disruption of the movement of emergency vehicles, and the cause of an undesirable increase in noise.
Courts have held public agencies liable for personal injuries resulting from faulty design. Because speed bumps have considerable potential for liability suits, many officials have rejected them as a standard traffic control device on public streets.
In addition, tests of various experimental designs have demonstrated the physical inability of a speed bump to successfully control all types of light-weight and heavy-weight vehicles. The drive of a soft sprung sedan is actually encouraged to increase speed for a better ride over a bump that may cause other motorists to lose control.
Mlipuko wa kasi ni hatari kubwa kwa wasio na tahadhari, changamoto kwa daredevil, usumbufu wa harakati za magari ya dharura, na sababu ya ongezeko lisilohitajika la kelele. Mahakama zimeweka mashirika ya umma kuwa na hatia ya majeraha ya kibinafsi yanayotokana na muundo usiofaa. Kwa sababu vifungo vya kuingilia mwendo vinaweza kusababisha kesi za kisheria, maofisa wengi wamevikataa kuwa vifaa vya kawaida vya kudhibiti trafiki barabarani. Kwa kuongezea, majaribio ya miundo mbalimbali ya majaribio yameonyesha kutokuwa na uwezo wa kimwili wa bumper ya kasi ya kudhibiti kwa mafanikio aina zote za magari ya uzito mwepesi na nzito. Kwa mfano, gari la aina ya soft-sprung limependekezwa kuongeza mwendo ili kuweza kuendesha gari kwa urahisi zaidi kwenye mteremko ambao unaweza kuwafanya madereva wengine wa gari wapoteze udhibiti.
