A roadway hazard warning assembly for enhancing visibility of a disabled vehicle on a roadway includes a vehicle that has been disabled on the side of a roadway. A warning flag is positionable on the vehicle when the vehicle becomes disabled on the roadway. The warning flag has light reflecting properties for reflecting light from headlights of oncoming traffic. In this way the warning flag can alert the oncoming traffic to the disabled vehicle. A plurality of fastening straps is provided and each of the fastening straps is removably coupled between the warning flag and the vehicle for retaining the warning flag on the vehicle.

Reflective, self-supporting road signaling device comprised of a support piece (A) and a signaling plate (B). The support piece (A) is made of a rigid triangular element with a clamp fastening onto the upper part of a vehicle window to support the signaling plate (B). As for the signaling plate (B), it is comprised of a long rectangular piece with a large positioning area for the reflective element (8). To ensure the signposted vehicle is easily seen by traffic on its same side, a reflective arrow changing color between red and white, with the arrow vertex as far as possible from the vehicle that carries it, is used.

A self-propelled warning device used for road safety includes a bracket, a warning sign mounted to an upper side of the bracket, and at least one driving mechanism. The driving mechanism includes a supporting leg, a driving unit, and a wheel. The supporting leg includes a receiving portion, the receiving portion defines an accommodating space. The driving unit is accommodated in the accommodating space. The wheel is mounted on the receiving portion and is drivingly connected to the driving unit. The wheel is driven by friction of the driving unit. The driving mechanism is also disclosed.

A mobile connectivity and self-generating illumination electric scooter comprises a step-through frame, and is operable as a plug-in electric vehicle with two or three wheels operational inside the wheels. A rechargeable battery stores electricity to drive the electric motor. The scooter also includes: a glossy finish, a rectangular front frame member, an aerodynamic manual brake fin, a communication device support member, detachable floor and front panels having multiple colors and designs, On/Off digital locking system, an accelerator handle and a brake handle differentiated by color; and further, an integral computer, an integrated router forming a Wi-Fi hotspot, a daytime running lamp, a help switch, a sound system, a camera for livestream and social media synchronization, a communication device charger, an integral GPS. The mobile communication device is in communication with, and controls at least one of: the integral computer, the Wi-Fi hotspot, speaker system, camera, help switch, and the GPS.

A warning device or apparatus for use during roadside stops, with means to display one or more warning messages on the front of the warning device or apparatus at a height to be easily and quickly seen by oncoming drivers. The warning device may be a warning triangle, although other shapes may be used as appropriate according to the customs or laws for particular regions or areas. One or more message plates can be mounted on the warning device, with various messages selected according to the circumstances. An electronic message board may be similarly mounted.

A safety warning sign, when not in use, is rolled and stored inside to case, and in the event of emergency, when a driver opens the trunk and then opens the case by pulling a cover with a finger while the case is attached and affixed to the edge of the trunk by means of a magnetic body of an attachment member connected to the case, the safety warning sign stored in the form of a roll inside the case is, simultaneously as the case is opened, automatically spread open by its own weight (gravity) and deployed, thus allowing the driver, even in the state of panic from an accident, to easily and rapidly install the car safety warning sign and quickly escape to safety.

The invention discloses an ejection type safety warning sign for car, having a polyhedral structure for suppressing tumbling in a free state, capable of being restrained into tubular storage state by external force, and automatically releasing as polyhedral structure when external force disappears; polyhedral structure having warning marker on surface. A ejection system comprises: warning sign; launch tube having inner cavity for accommodating warning sign in tubular storage state; pressure tank communicated with end of launch tube; solenoid valve disposed between launch tube and pressure tank; controller connected to solenoid valve; launch tube having piston for pushing warning sign. When sudden situation occurs during driving, driver can press ejection button of warning sign while braking, so that warning sign can be ejected and stays near position of braking. Location of warning sign is at distance from position parking, eliminating take warning sign, promptly alerting rear car, reducing rear-end accidents.

Aspects and implementations of the present disclosure relate to performance and safety improvements for autonomous trucking systems, such as reactive suspensions for maximizing aerodynamic performance and minimizing mechanical impact from road imperfections, automated placement of emergency signaling devices, and techniques of enhanced illumination of stopped and stranded vehicles.

A warning device used for road safety includes a warning sign and a driving mechanism. The driving mechanism includes a base, a driving unit, at least one wheel, a plurality of supporting units, and a plurality of driving members. The driving unit is accommodated in the base. The at least one wheel is connected to and driven by the driving unit. The plurality of supporting units are movably connected to the base. The plurality of driving members can manipulate the supporting units. Each of the supporting units is movable between a receiving or retracted position and a supporting or extended position. For stability in placement, the device can be lifted a small distance above the road by the supporting units when these are deployed. The driving mechanism is also disclosed.
