Minister of Transport v Du Toit

The first respondent was seriously injured as a passenger when the vehicle driven by her husband mistakenly left the N1 freeway at the Grasmere toll gate near Johannesburg and drove through an unlit ‘T’ intersection at the end of an off-ramp, plunging down an embankment. The driver believed he was still on the freeway due to confusing and inadequately positioned road signage. The respondent sued the South African Roads Board (later substituted by the Minister of Transport) for damages, alleging negligent failure to erect and maintain adequate road signs. The Minister joined Toll Road Concessionaries (Pty) Ltd and the driver as third parties. The trial court separated the issue of negligence and found the Minister negligent, apportioning fault at 20% to the road authority and 80% to the driver. The Minister and Toll Road Concessionaries appealed.

The appeal was dismissed. The finding that the Minister was 20% liable and the driver 80% liable was confirmed. The appellants were ordered jointly and severally to pay the first respondent’s costs.

The case is significant for clarifying the standard of care owed by road authorities in South African delict law, particularly regarding the adequacy, clarity, and positioning of road signage. It confirms that authorities cannot rely solely on the assumption of a perfectly attentive driver and that poorly designed or positioned signage may found liability even where a driver is substantially negligent. The judgment also illustrates the application of contributory negligence and apportionment of damages in road accident cases.
